Texas AG Ken Paxton steps up Senate bid against GOP Sen. Cornyn

Paxton's campaign rallies and ads aim to unseat the four-term Republican senator

Feb. 17, 2026 at 8:55pm

Texas Attorney General Ken Paxton is ramping up his campaign to unseat four-term Republican Sen. John Cornyn, setting up one of the most contentious GOP primaries this year. Paxton, who has the look of the party's front-runner despite facing ethical and personal questions, is betting that his defiance of his own party's leaders and aggressive litigation for conservative priorities will help him overcome concerns that voters have forgiven until now.

Why it matters

Paxton's bid to unseat the incumbent Cornyn has set up a high-stakes Republican primary in Texas, with national GOP leaders concerned that Paxton as the nominee would require significantly more resources to defend in the general election than the more establishment-friendly Cornyn.

The details

Paxton is scheduled to hold his first major campaign rally on Monday night, part of a stepped-up effort that includes a new TV ad featuring praise from former President Donald Trump. Until now, Paxton has run a lower-profile campaign, spending relatively little money. But with early voting starting Tuesday for the March 3 primary, Paxton is making stops across Texas this week. Paxton is betting that his defiance of GOP leaders and aggressive litigation for conservative causes will help him overcome ethical and personal questions, including being impeached on fraud charges in 2023 and allegations of marital infidelity made by his wife.
