• Senate Republicans voted to proceed with leadership elections over objections from a handful of members led by Ron Johnson, then re-elected Thune without opposition [1].
  • Sanders said "the time is now for change, and I will not be supporting Chuck to be re-elected as the Democratic leader"; Schumer said he would be "proud to lead" the caucus as majority leader [2].
  • Democrats will control at least 54 seats in the new Congress and are expected to hold leadership elections in early December [3].

Senate Republicans re-elected John Thune as their leader on Tuesday, rejecting an effort to postpone leadership elections after the party lost its majority in last week's midterms [1]. Thune, who ran unopposed, will become minority leader when the 120th Congress convenes in January, and the rest of his leadership team is on track to keep their posts, Semafor reported [1][3].

Sen. Ron Johnson of Wisconsin led the push for a delay and walked out in protest after losing a procedural vote that he said "wasn't particularly close" [1]. "When you have this kind of defeat, you'd like to at least give people an opportunity to think about it," Johnson said, adding that his objection was not about Thune [1]. With no challenger in sight, most Republicans opposed leaving the leadership question open, according to Semafor [1].

Schumer faces open dissent

On the Democratic side, Sanders said he would not support Chuck Schumer for another term as leader. "The time is now for change, and I will not be supporting Chuck to be re-elected as the Democratic leader," the Vermont independent said, adding, "I like Chuck" [2]. Sen. Elissa Slotkin of Michigan, who stood beside Sanders, also said she would not back Schumer without a concrete plan for change: "I'm a no until and unless I see that from anyone" [2][3].

No one has formally challenged Schumer. Sen. Chris Van Hollen of Maryland said he is "in listening mode and haven't shut the door," and that "we shouldn't have a coronation" [3]. Schumer, who needs a majority of the caucus, said: "We have great unity in our caucus, and I'll be proud to lead it as majority leader" [2]. Democrats gained a net of at least seven seats, with races in Mississippi and Alaska still being counted, NBC News reported [2].

What the leadership votes mean for tech and markets

The majority leader controls the Senate floor: which bills get votes, how fast nominees move and how much time goes to spending and tax fights. That schedule will shape whether AI rules, chip export controls, crypto market-structure legislation and tariff oversight advance in 2027, alongside the agendas of incoming committee chairs such as Elizabeth Warren at Senate Banking. MLQ.ai has laid out what a Democratic Congress means for AI, chips, crypto and Big Tech. In the House, Republicans have already chosen Jim Jordan as minority leader.
