The 2024 election was big not just for control of the federal government, but also various state governments. Before the election, Cooper identified 10 state legislative chambers that were in danger of flipping control. How did those elections turn out?
Generally speaking, pretty well for Republicans. The GOP expanded their majorities in the New Hampshire state Senate and state House, giving them a workable trifecta when paired with Republican Gov.-elect Kelly Ayotte. (Republicans technically had a trifecta in New Hampshire before too, but their majority in the state House was so narrow they had trouble getting things done.) They also expanded their majorities in the Arizona state Senate and House and kept control of the Wisconsin Assembly under a newly un-gerrymandered map, although Democrats whittled the GOP majority down to 54-45. But their biggest win was flipping control of the Michigan state House, breaking the Democratic trifecta there.
Democrats had some victories too, though. They retained their uber-narrow 102-101 majority in the Pennsylvania state House, even as Trump was carrying the state. They won the special election that determined control of the Minnesota state Senate, albeit by a too-close-for-comfort margin of 52% to 48%. And a group of Democrats, independents and moderate Republicans announced they would form a coalition to govern the Alaska state House, replacing a Republican-dominated coalition.
One state legislative chamber remains unresolved: the Minnesota state House. According to the AP, Republicans have won 67 seats, Democrats have won 65 seats and two seats (House Districts 14B and 54A) are heading for recounts. Currently, Democrats lead in House District 14B by 191 votes, and in House District 54A by just 14 votes. If Democrats hold onto both leads, the chamber would be tied, and the two parties would have to hammer out a power-sharing agreement. If Republicans win just one, they would obviously win a majority. Either way, though, Democrats will lose full control over Minnesota state government.
