After midterm rout, Republicans can still confirm a Supreme Court justice, but at what cost?

Key Points:

• Democrats secured at least a 54-seat majority in the Senate in the 2026 midterms, limiting President Donald Trump's opportunity to appoint new Supreme Court justices and maintain conservative control.
• Justices Samuel Alito and Clarence Thomas, the court's oldest members with strong conservative ties, are potential retirees; their departure could trigger a contentious confirmation battle given the new Democratic Senate majority.
• Republicans have a narrow window between Election Day and January 3, 2027, to confirm any nominee if a justice retires soon, but Democrats are expected to resist the process, despite Republicans having curtailed some Senate delaying tactics.
• A Republican push to confirm a Supreme Court nominee during the lame-duck session would likely provoke a historic and intense conflict, with Democrats citing past Republican obstruction of Merrick Garland's 2016 nomination as precedent.
• Such a battle could deepen public distrust in the Supreme Court, energize calls for court reform including potential expansion, and may ultimately backfire on Republicans by providing Democrats with justification to reshape the court.
