Republicans and Democrats Battle for House and State Courts

The Republican Party and the Democratic Party are engaged in high-stakes contests for legislative and judicial power during the 2026 midterm elections. In the U.S. House of Representatives, Republicans are defending a narrow majority in a cycle where all 435 seats are contested. Analysts expect the outcome to hinge on roughly 21 competitive races across battleground states, including Pennsylvania, Michigan, and Arizona, following 2025 redistricting efforts in states like Texas, Florida, and California.

Simultaneously, partisan battles have intensified over state supreme courts across 31 states, with 63 seats contested. Both parties are investing heavily in these judicial races to secure influence ahead of the 2030 census and subsequent redistricting. Montana represents the only state where a single election could flip court control, as Republican-backed Dan Wilson challenges liberal Amy Eddy for the seat of retiring Justice Beth Baker.

Other critical judicial targets include Texas, where Democrats are attempting to gain a foothold on an all-Republican court, and Ohio, where Republicans seek to remove the final Democratic justice. Voters are also deciding on retention elections and ballot measures, including a Montana proposal to enshrine nonpartisan elections in the state constitution.
