Trump’s Endorsement of Ken Paxton in Texas Senate Runoff President Donald Trump endorsed Texas Attorney General Ken Paxton in the Republican Senate runoff against incumbent Sen. John Cornyn, marking a significant shift in the race. Trump’s endorsement came after months of pressure from Senate Republicans, including Senate Majority Leader John Thune (R-S.D.), to back Cornyn. However, Trump opted for Paxton, a hardline ally, despite Cornyn’s longstanding GOP establishment support. The endorsement was announced during Trump’s "10-day GOP revenge tour," where he targeted Republicans who opposed his agenda, including Sen. Bill Cassidy (R-La.) and Sen. Thom Tillis (R-N.C.) .
The move has sparked backlash within the GOP, with senators like Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska) criticizing Paxton as "ethically challenged" and expressing disappointment in Trump’s decision. Trump’s endorsement is seen as a direct challenge to Cornyn, who had secured the most votes in the March primary but failed to reach a majority, forcing a runoff. Polls suggest a tight race between Paxton and Cornyn, with Democratic nominee James Talarico leading both in recent surveys .
Impact on GOP Unity and Senate Dynamics Trump’s endorsement of Paxton has deepened divisions within the GOP, particularly among Senate Republicans who rely on Trump’s support to advance their agenda. The decision is viewed as a retaliatory move against Cornyn, who Trump reportedly abandoned after the failure of the SAVE Act, a key immigration bill. Trump’s frustration with the Senate, including its rules and refusal to abolish the filibuster, has further strained relations. Senate Republicans now face a "combustible environment" as they attempt to pass must-pass legislation, including funding for ICE and Border Patrol, before June deadlines .
The Texas Senate race is rated "likely Republican" by the Cook Political Report, but Trump’s endorsement of Paxton could create vulnerabilities for the GOP in November. Democrats have seized on the endorsement as an opportunity to criticize Paxton’s record, including allegations of antisemitism linked to a Texas candidate he supports . Early voting in the runoff ends Friday, with Election Day on May 26.
