**John Cornyn has not endorsed any candidate in the 2026 Texas Senate general election and has shown no recent movement toward doing so.** After losing the Republican primary runoff to Ken Paxton in May, Cornyn stated support for the Republican ticket but declined to campaign for or direct funds to Paxton, describing him as a poor campaigner. Recent weeks have featured heightened tensions, with President Trump publicly criticizing Cornyn and strategist Karl Rove for failing to rally behind Paxton amid a tight race against Democrat James Talarico. Polling shows Talarico with a narrow edge heading into the November 3 vote. This pattern of distance from the nominee and absence of any public signals toward other contenders has shaped trader consensus around no endorsement occurring.
