Potential ties

A total of 61 state legislative chambers around the country have an even number of members, raising the possibility of a tie between the two major parties. In some instances, a bipartisan coalition of legislators is formed to act as leadership.[1] This tactic has not been the universal approach, however; some legislative bodies have used a coin toss, gubernatorial choice, shared time, choosing co-leaders, or dividing chairperson positions between the parties.[2]
