Texas Sen. John Cornyn outraised his Republican challenger, Attorney General Ken Paxton, by $1 million during the first three months of what’s becoming one of the most hotly contested primary battles of the 2026 midterm elections.

Cornyn will need to use his deep coffers to overcome an early polling deficit to Paxton, who is looking to deny the GOP incumbent’s bid for a fifth term.

Sen. John Cornyn has established a wide fundraising advantage over his Texas Republican primary opponent state Attorney General Ken Paxton, according to financial figures obtained by Axios. Why it matters: Cornyn is facing a more serious primary threat than any other senator up for election next year — and will need every dollar he can get.
