President Donald Trump endorsed Texas Attorney General Ken Paxton (R-TX) on Tuesday, May 19, 2026 [2], for the U.S. Senate.
The move shifts the dynamics of the Republican primary runoff, pitting a high-profile ally of the former president against an incumbent senator. This endorsement could redefine the GOP's strategy in Texas and influence the balance of power in the U.S. Senate.
Trump said that Paxton is a stronger ally and better positioned to support his legislative agenda and the party's Senate majority. The endorsement comes as a significant blow to incumbent U.S. Senator John Cornyn (R-TX), who has spent over a year courting Trump’s support [3].
Republican leaders said that the endorsement may jeopardize the seat in the general election. Some party officials said that backing Paxton could hurt the GOP’s chances of retaining the seat when facing Democratic challengers.
Other observers said the endorsement puts the seat in play for Democrats. Some analysts said that the move implies Cornyn has debased himself in his attempts to secure Trump's backing.
The Texas Republican primary for the U.S. Senate seat has become a focal point for the national party. The clash between Paxton and Cornyn represents a wider struggle within the GOP between established incumbents and those more closely aligned with Trump's specific political movement.
“Trump said that Paxton is a stronger ally and better positioned to support his legislative agenda.”
This endorsement signals a preference for ideological loyalty over incumbency within the Texas GOP. By backing Paxton, Trump is testing the influence of his endorsement in a runoff scenario, which may either solidify a more populist wing of the party or create a vulnerability that Democrats can exploit in the general election.
