Republicans currently hold a Senate majority under John Thune, who assumed the leadership role in 2025, while Chuck Schumer serves as Democratic minority leader. The closely matched prices for Thune and Schumer reflect uncertainty over the November 2026 elections, where 33 seats are contested and control of the chamber remains competitive. Recent polling and candidate recruitment in key states highlight multiple paths for Democrats to flip the majority, which would elevate Schumer, while Republican retention would favor Thune's continuation. Internal party dynamics, including some Republican criticism of Thune and Democratic primary tensions, add variables that could shift caucus support after the vote count determines the majority party.
