The Texas Senate primary race has become a focal point for Republican infighting, pitting incumbent Sen. John Cornyn against state Attorney General Ken Paxton in a May 26 runoff. The contest highlights divisions within the GOP between establishment figures and America First conservatives.

Paxton, a staunch ally of President Donald Trump, has positioned himself as the candidate committed to election integrity and border security. Cornyn, seeking a fifth term, represents the traditional Republican leadership and faces criticism for his anti-Trump base stance on key issues.
