In 2018, elections for governor were held in 36 states.

Republicans won 20 of the 36 seats up for election, and Democrats won 16. Democrats gained seven seats that were held by Republicans heading into the election, unseating incumbents in Illinois and Wisconsin and picking up open seats in Kansas, Maine, Michigan, Nevada, and New Mexico. Republicans picked up the open gubernatorial seat in Alaska, which had previously been held by independent Bill Walker. Following the election, Republicans held 27 gubernatorial seats to Democrats' 23.

Heading into the 2018 elections, the majority of governorships were held by Republicans, with 33 governorships to Democrats' 16, and one independent seat in Alaska. Of the 33 Republican-held seats, 26 were up for election, of which 13 were open. Of the 16 Democratic-held seats, nine were up for election, of which four were open.

2018 election analysis and context

Heading into the election, 33 of the 50 governorships were held by Republicans and 16 by Democrats, plus Alaska’s independent. The 2018 results increased the total number of Democratic governors to 23 and reduced the GOP total to 27.

The new gubernatorial count most closely resembles the landscape after the 2010 election. The last time the Democratic Party had more than 20 governorships was in 2010, when they held 26 heading into that cycle. Republicans entered 2010 with 23 governorships and emerged with 29 following that midterm election.

Incumbents were seeking re-election in 10 of the 36 races contested in 2018, six of them Republicans and four Democrats.

All four Democratic incumbents won their races: New York (Andrew Cuomo), Oregon (Kate Brown), Pennsylvania (Tom Wolf), and Rhode Island (Gina Raimondo).

Republican incumbents won in Arizona (Doug Ducey), Iowa (Kim Reynolds), Nebraska (Pete Ricketts), and New Hampshire (Chris Sununu).

Two Republican incumbents lost:

• Illinois: Businessman J.B. Pritzker (D) defeated incumbent Bruce Rauner (R).

• Wisconsin: Tony Evers (D) defeated incumbent Scott Walker (R).

In five other races without incumbents running, seats held by Republicans were taken by Democrats:

• Kansas: State Sen. Laura Kelly (D) defeated Secretary of State Kris Kobach (R). Incumbent Gov. Jeff Colyer (R), who took office following former Gov. Brownback's resignation, ran for a full term but was defeated by Kobach in the August 7 primary, leaving the seat open.

• Maine: Maine Attorney General Janet Mills (D) defeated businessman Shawn Moody (R) and state Treasurer Teresea Hayes (I). Incumbent Gov. Paul LePage (R) was term-limited, leaving the seat open.

• Michigan: Former state Senate Minority Leader Gretchen Whitmer (D) defeated Michigan Attorney General Bill Schuette (R). Incumbent Gov. Rick Snyder (R) was term-limited, leaving the seat open.

• New Mexico: U.S. Rep. Michelle Lujan Grisham (D) defeated U.S. Rep. Steve Pearce (R). Incumbent Gov. Susana Martinez (R) was prevented by term limits from seeking a third term, leaving the seat open.

• Nevada: Clark County Commissioner Steve Sisolak (D) defeated Nevada Attorney General Adam Laxalt (R). Incumbent Gov. Brian Sandoval (R) was term-limited, leaving the seat open.

In the Alaska governor’s race, former state Sen. Mike Dunleavy (R) defeated former U.S. Sen. Mark Begich (D). Incumbent Gov. Bill Walker (I) suspended his re-election campaign on October 19, 2018, saying in a statement, "In the time remaining, I believe we cannot win a three-way race,” leaving the seat open for the two major-party candidates.

The first of the maps below shows the results of the 2018 gubernatorial elections. The second shows the total gubernatorial partisan affiliations following the 2018 elections.

State government trifectas

Democrats emerged from the 2018 elections with a net gain in state government trifectas—where one political party holds the governorship, a majority in the state senate, and a majority in the state house in a state's government. Republicans retain a net advantage of eight trifectas over Democrats. The new trifecta count stands at 14 Democratic, 22 Republican, and 14 divided.

Entering the 2018 midterm election, Republicans had a +14 state trifecta lead: of 34 states with trifectas, 26 were Republican and eight were Democratic. But after the votes were counted, Democrats increased their trifecta total with a net gain of six, and Republicans declined to 22 trifectas (a net loss of four). States with divided government (i.e., no trifecta for either major party) declined to 14.

This outcome is similar to the trifecta balance following the 2014 midterm election, which left Republicans with 24 trifectas, Democrats with 13, and 13 states with no trifecta advantage for either major party. After the 2010 midterms, 25 states had no trifectas, Republicans had nine, and Democrats had 16.

In two cases where Democrats gained trifectas, and in one case where Republicans lost a trifecta, Democrats won open gubernatorial races that had been vacated by Republican incumbents who could not seek re-election due to term limits.

The total number of trifectas—36—is almost in line with the 37 trifectas in 2013 and 2014, the most trifectas in recent history.

Change in state government trifectas, 2018 elections
Trifecta status	Before	After	Net
Democratic trifectas	8	14	+6
Republican trifectas	26	22	-4
Divided government	16	14	-2

The six Democratic flips from divided government to trifecta control in 2018 were in:

• Colorado: Democrats won control of the Colorado Senate.
• Illinois: Democrats won the governor’s office with businessman J.B. Pritzker (D) defeating incumbent Bruce Rauner (R).
• Maine: Democrats won control of the Maine Senate and took the governor’s office with Maine Attorney General Janet Mills (D) defeating businessman Shawn Moody (R) and state Treasurer Teresea Hayes (I). Incumbent Gov. Paul LePage (R) was term-limited, leaving the seat open.
• New Mexico: Democrats won the governor’s office with U.S. Rep. Michelle Lujan Grisham (D) defeating U.S. Rep. Steve Pearce (R). Incumbent Gov. Susana Martinez (R) was prevented by term limits from seeking a third term, leaving the seat open.
• New York: Democrats won control of the New York Senate.
• Nevada: Democrats won the governor’s office with Steve Sisolak (D) defeating Adam Laxalt (R).

In each of the four states where Republicans lost trifectas the balance of power became divided:

• Kansas: Democrats won the governor’s office with State Sen. Laura Kelly (D) defeating Secretary of State Kris Kobach (R). Incumbent Gov. Jeff Colyer (R), who took office following former Gov. Sam Brownback's resignation in January 2018, ran for a full term but was defeated by Kobach in the August 7 primary, leaving the seat open.
• Michigan: Democrats won the governor’s office with former state Senate Minority Leader Gretchen Whitmer (D) defeating Michigan Attorney General Bill Schuette (R). Incumbent Gov. Rick Snyder (R) was term-limited, leaving the seat open.
• Wisconsin: Democrats won the governor’s office with Tony Evers (D) defeating incumbent Scott Walker (R).
• New Hampshire: Democrats won control of the House and Senate.

Overall, 10 total states saw a trifecta status change in some way.

• Colorado: divided government to Democratic trifecta
• Illinois: divided government to Democratic trifecta
• Kansas: Republican trifecta to divided government
• Maine: divided government to Democratic trifecta
• Michigan: Republican trifecta to divided government
• Nevada: divided government to Democratic trifecta
• New Hampshire: Republican trifecta to divided government
• New Mexico: divided government to Democratic trifecta
• New York: divided government to Democratic trifecta
• Wisconsin: Republican trifecta to divided government

List of gubernatorial elections

The table below lists the states with gubernatorial elections in 2018, whether or not those states had a state government trifecta or triplex prior to the 2018 election, the incumbent and the incumbent's party prior to the election, and whether or not the incumbent ran for re-election.

A state government trifecta is a term to describe single party government, when one political party holds the governorship, a majority in the state senate, and a majority in the state house in a state's government. State government triplexes describe when one political party holds the following three positions in a state's government: governor, attorney general, and secretary of state.

Most states impose some form of term limits on governors; of those that do, all but Virginia limit a governor to two four-year terms or to eight years in office. Although most states' term limit laws allow a governor who has served two terms to be elected once again after time has elapsed, some states impose a lifetime term limit like that on the presidency.

Battleground elections

Ballotpedia identified 25 gubernatorial elections as battleground races. Of the 26 Republican-held seats up for election, 16 were battlegrounds, including 10 of the 13 open seats. Of the nine Democratic-held seats up for election, eight—all except Hawaii—were battlegrounds. Alaska's independent-held seat was also a battleground.

Among the battleground races in 2018 was the Illinois gubernatorial election, in which Republican Gov. Bruce Rauner was defeated by Democrat J.B. Pritzker. Both candidates contributed over $50 million to their own campaigns. Between Election Day 2014 and Election Day 2018, Pritzker contributed $171.5 million to his own campaign while Rauner contributed $67.8 million to his run. The overall fundraising in the election—$285.0 million—was higher than any other gubernatorial election in U.S. history, surpassing the 2010 California gubernatorial election's $251.9 million fundraising total.

In the Georgia race, former state House Minority Leader Stacey Abrams (D) vied to become the first black woman to win a governor's race in U.S. history. She was defeated by Secretary of State Brian Kemp (R), who beat four Republican rivals in the primaries and secured an endorsement from President Donald Trump.

The nation's only independent governor, Bill Walker of Alaska, suspended his re-election bid on October 19, 2018, after the resignation of his lieutenant governor and running mate Byron Mallott (D). Walker's withdrawal set the stage for a contest between former Sen. Mark Begich (D) and former state Sen. Mike Dunleavy (R), leading to the Republican Party's only gubernatorial pickup in 2018.

Outside race ratings

The following table compared gubernatorial race ratings from The Cook Political Report, Sabato's Crystal Ball, and Inside Elections prior to the November 2018 election.

About the office

See also: Governor (state executive office)

In the United States, the title governor refers to the chief executive of each state. The governor is not directly subordinate to the federal authorities but is the political and ceremonial head of the state. The governor may also assume additional roles, such as the commander-in-chief of the National Guard when the role is not federalized. The governor may also have the ability to commute or pardon a criminal sentence.

In all states, the governor is directly elected and, in most cases, has considerable practical powers. Notable exceptions with weak governorships include the office of the governor in Texas, though this may be moderated by the state legislature and, in some cases, by other elected executive officials. Governors can veto state bills. The specific duties and powers vary widely between states.

Compensation

According to compensation figures for 2023 compiled by the Council of State Governments in the Book of the States, the highest salary for a governor was $250,000 in New York while the lowest was $70,000 in Maine. To view the compensation of a particular governor, hover your mouse over the state.

Staff size

According to figures for 2022 compiled by the Council of State Governments in the Book of the States, gubernatorial offices range in size from 9 staffers in Nebraska to 277 staffers in Texas.

Involvement in budget proposals

Although all governors have some involvement in the process of developing a state budget, the specific level of involvement differs from state to state. According to information published in the 2022 Book of the States, 24 governors share responsibility for developing a budget proposal, while 11 governors have full responsibility for developing an initial budget proposal and the remaining 15 have full responsibility for developing a budget.

Term limits

See also: States with gubernatorial term limits

Most states impose some form of term limits on governors; of those that do, all but Virginia limit a governor to two four-year terms or to eight years in office. Although most states' term limit laws allow a governor who has served two terms to be elected once again after time has elapsed, some states impose a lifetime term limit like that on the presidency. Although Vermont and New Hampshire do not have term limit laws, they are the only states whose governors serve two-year terms rather than four-year terms.

Line-item veto powers

The term line-item veto refers to the ability of a governor or other chief executive to veto specific parts of a bill while signing the rest of the bill into law. Currently, 44 states grant their governors line-item veto powers.

Fundraising

Both Democrats and Republicans have organizations which have been formed to support and help elect governors of their respective parties. The Democratic Governors Association and Republican Governors Association are IRS-designated 527 political organizations that serve as resources for each party's gubernatorial candidates and elected governors.

The following is a breakdown of the DGA's and RGA’s receipts for 2017, as reported by each organization.

DGA's and RGA's reported contributions
Year	Democratic Governor’s Association	Republican Governor’s Association
2017	$41,000,000	$63,200,000

Media coverage and analysis of the 2018 elections

This section provides an overview of media coverage of gubernatorial elections across the country. Selected articles are presented as a jumping-off point for deeper exploration of media coverage and as an overview of narratives that have emerged surrounding the elections.

• Perry Bacon Jr., FiveThirtyEight (November 7, 2018):

"There are six states Obama won in 2012 that flipped to Trump in 2016 — Florida, Iowa, Michigan, Ohio, Pennsylvania and Wisconsin. Our model suggested Democrats had a great chance to win all six, which would have been a huge coup for the party. Instead, Republicans won in Florida, Iowa and Ohio, while Democrats won Michigan, Pennsylvania and Wisconsin.

Republicans entered this election with control of both the state legislature and the governor’s office in all of these states but Pennsylvania. They will remain totally in charge in Florida, Iowa and Ohio. That gives them virtually unfettered power not only on policy but also in drawing district lines for state and federal legislative races. But it’s big for Democrats to have won in Michigan and Wisconsin and broken up so-called trifectas in those states."

• Margaret Newkirk, Bloomberg (November 7, 2018):

"Democrats lost their bid for history in Florida, with a star-power candidate failing to become the state’s first black governor. But the party won a split decision on governors’ seats in the Midwestern states that sent Donald Trump to the White House. And one of the most high-profile races, in Georgia, was possibly headed to a recount.

In all, Democrats picked up at least seven of 26 GOP-held gubernatorial seats, a shift that could complicate Trump’s re-election hopes and alter the nation’s political landscape for the next decade. GOP hopes for a rare pickup evaporated Wednesday when Connecticut Republican Bob Stefanowski, after leading for much of election night, conceded to Democrat Ned Lamont.

The victories tamed a long, Tea Party-fueled winning streak that had given Republicans control of 33 governor’s mansions, the most since 1928. That success became the party’s biggest vulnerability, with Republicans defending nearly three times as many governor’s mansions this year as Democrats."

• Dan McLaughlin, National Review (October 19, 2018):

"The most optimistic trends for the GOP are in Arizona, Oklahoma, Nevada, and Georgia, three of which seem to be moving in the direction of the state’s recent partisan lean. The mirror image is happening in Rhode Island, Illinois, Pennsylvania, Minnesota, and Oregon, and the trendline in Ohio is not encouraging.

If I had to project today, I’d see Republicans picking up Alaska and taking a net loss of about five or six governorships, bringing them down to 27 or 28 of the 50 states. But there are still a lot of races that are either in play, or still have too little reliable polling to call. There were more Election Day surprises in 2014 in the governors’ races than the Senate races, and we should not be surprised to be surprised again."

• Sally Persons, RealClearPolitics (October 17, 2018):

"While the nation’s midterm focus has primarily been on Republican efforts to maintain control of the House and Senate, the GOP is also playing defense with a number of key gubernatorial seats. Many of them are tossups in the final weeks before Election Day -- and are taking place in states that also have a Senate race. Both major political parties are banking their hopes on ticket-splitting voters.

Ohio, no stranger to national politics, is a case in point. Incumbent Sen. Sherrod Brown has a hefty lead over his Republican opponent, Rep. Jim Renacci, but the state also has a competitive gubernatorial race. RealClearPolitics shows Brown up by 16 points in the latest poll average, while Democratic gubernatorial candidate Richard Cordray has a mere 2.7 point lead against Republican Mike DeWine. Ohio Democrats are hoping that Brown’s coattails will help Cordray -- the former head of the Consumer Financial Protection Bureau -- while Republicans are banking on continued visits from President Trump to help them energize their base."

• Amber Phillips, The Washington Post (October 10, 2018):

"Nine of the 10 races most likely to flip parties are held by Republicans, spanning the country from Iowa to New Mexico. And while none makes our top 10, open seats in traditionally conservative states, such as Georgia, Kansas, South Dakota and Oklahoma, are all competitive.

The catch is that however many governor’s races the Democrats win, they will be only chipping away at Republicans' historic level of success. Republicans control 33 governor’s mansions, a near record, and those include blue and swing states. And it’s not impossible that Republicans might also pick up control of a state like Connecticut, though that one has fallen off our top-10 list."

• Alan Greenblatt, Governing (October 3, 2018)

"In the blue states of Connecticut and Oregon, Republicans have fighting chances at winning governors' offices currently held by Democrats.

In Connecticut, outgoing Democrat Dannel Malloy is one of the least popular governors in the country, with an approval rating of around 20 percent. He's raised taxes substantially, yet the state faces a budget shortfall in the neighborhood of $2 billion. Connecticut remains wealthy, but it's been shedding jobs and population as job creation has lagged well behind the nation as a whole....

The contours of the race in Oregon are different. There, GOP state Rep. Knute Buehler is running against Democratic incumbent Gov. Kate Brown by presenting himself as a moderate. Most prognosticators give Brown the edge, but Real Clear Politics changed its rating of the race last week to tossup."

• W. James Antle III, The Washington Examiner (September 18, 2018):

"New York Gov. Andrew Cuomo’s crushing victory over actress and activist Cynthia Nixon brought down the curtain on a long primary season last Thursday. Now the candidates are in place for the midterm elections as his fellow Democrats try to rebuke President Trump, recapture Congress and chip away at the Republicans’ stranglehold on the nation’s governorships.

As is often the case with politics in the Trump era, however, nothing is ever easy. Democrats are defending 26 Senate seats to the Republicans’ nine, including 10 in states Trump won in 2016. In about half of these states, the president is still popular, creating the possibility that the GOP will actually expand its narrow 51-49 majority in the upper chamber. Some of the most popular governors in the country are Republicans, including incumbents running for reelection this year in Massachusetts and Maryland, the bluest of states."

Historical control

In 1977, the Democratic Party held a total of 37 governorships to the Republican Party's 12. Following the elections of 1980, the Democratic lead in governorships narrowed to 27 to the Republican Party's 23. The 1986 midterm elections also saw an increase in Republican governorships, bringing the party to 24 governorships compared to the Democrats' 26. The Republican Party would take the national lead in governorships following the midterm elections of 1994; in 1995, there were 30 Republican governors to 19 Democratic governors.

The Republican lead in governorships would be maintained for just over a decade until the midterm elections of 2006; in 2007, there were 28 Democratic governors to the Republicans' 22. However, the Republican Party would regain its national majority in the 2010 midterm elections. Between 2010 and 2017, the number of Republican governors continued to increase, reaching a high point of 34 following West Virginia Gov. Jim Justice's switch to the Republican Party in August 2017.

Wave election analysis

See also: Wave elections (1918-2016)

The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?

Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.

Applying this definition to gubernatorial elections, we found that Republicans needed to lose seven seats for 2018 to qualify as a wave election.

The chart below shows the number of seats the president's party lost in the 11 gubernatorial waves from 1918 to 2016. Click here to read the full report.
