Hill leaders brace for difficult 2027 term

Senate Majority Leader John Thune (R-S.D.) is expected to retain his position for another two years, with his tenure likely marked by continued friction with the president and pressure from the party base. The future of the other major leadership roles on Capitol Hill remains tied to the outcome of the November election, creating a volatile environment for the next Congress. Speaker Mike Johnson (R-La.) faces the most uncertainty, as most of his colleagues do not expect him to remain in his role if Republicans lose the House majority. Johnson has been publicly entertaining his next moves in the campaign's final weeks, while Majority Leader Steve Scalise (R-La.) and Rep. Jim Jordan (R-Ohio) are widely viewed as top contenders to replace him if the chamber flips.

Thune's path to re-election as leader is complicated by internal party dynamics. Key allies, including DHS Secretary Markwayne Mullin, Sens. Steve Daines (R-Mont.), Marsha Blackburn (R-Tenn.) and John Cornyn (R-Texas), have departed or are in the process of departing the Senate. This exodus coincides with the arrival of a new cohort of House conservatives in the upper chamber, who are likely to prioritize rapid legislative action. MAGA influencers remain unhappy with Thune's reluctance to eliminate the filibuster or force through a voter-ID bill. Despite this, Senate Majority Whip John Barrasso (R-Wyo.), the top contender if Thune stepped down, has doubled down on his support. Sen. Rick Scott (R-Fla.) has not announced a third bid for leadership, but many Republicans suspect he will run, particularly after he backtracked on his support for Thune in September.

On the Democratic side, Senate Minority Leader Chuck Schumer (D-N.Y.) appears secure in his current role, though he faces a potential primary challenge from Rep. Alexandria Ocasio-Cortez (D-N.Y.) in 2028. Many Democrats expect Schumer to retire. His relationship with House Minority Leader Hakeem Jeffries (D-N.Y.) requires attention, as their approaches to funding the government diverged sharply in March 2025. These differences could be more difficult to manage if Democrats take the majority, especially if Jeffries struggles to maintain discipline among his progressive members. Jeffries does not appear to have formidable challengers for party leader but may face similar headaches regarding party unity.

The relationship between President Trump and Schumer remains complicated, but the president has indicated he sees Jeffries as someone he could work with. The next Congress is expected to bring significant challenges for all major leaders, with guaranteed long nights and short tempers for those who remain in power.
