Legislative chamber control and trifecta shifts on the 2026 ballot
Voters in 46 states will fill 6,139 of the nation’s 7,386 state legislative seats on Nov. 3, with 88 of 99 chambers holding elections. Republicans currently hold majorities in 51 of the chambers up this year and Democrats in 34, while a few are tied or run by power-sharing arrangements. Ballotpedia identified 18 battleground chambers and is monitoring possible changes to state government trifectas.
This cycle covers legislative elections in 46 states, with 88 of 99 chambers and 6,139 of 7,386 seats on the ballot. Of chambers holding elections, Republicans currently lead 51 and Democrats 34; Alaska’s two chambers use power-sharing, and Minnesota’s House is evenly divided. Across all state legislative chambers, Republicans hold 57, Democrats 39, and three are shared or tied.
Ballotpedia counts 18 battleground chambers: Republicans control 10, Democrats five, and three are tied or power-sharing. Nationally, there are 23 Republican trifectas, 16 Democratic trifectas, and 11 divided governments. Supermajorities currently exist in 19 Republican and eight Democratic states.
Because these races can alter chamber control, trifectas, and veto-proof margins, they may shape which policies advance on issues such as budgets, education, health, and election administration. Residents in battleground and trifecta states could see the clearest effects, while candidates, parties, and advocacy groups may adjust strategies. The results may also influence how much leverage governors have and how broadly state laws reflect one party’s priorities.
