In a brewing political battle, Texas Attorney General Ken Paxton has officially announced his primary challenge against long-serving Senator John Cornyn. This high-profile contest has seen early attacks exchanged between the two Republicans, with Paxton aiming to leverage his status as a Trump ally in a race characterized by deep divisions within the GOP. Support is emerging for Paxton, including endorsements from notable figures, as the rivalry intensifies and both candidates prepare for a contentious campaign. Analysts suggest this primary could be the most significant political fight in Texas since 2010, with implications reaching far beyond state lines.
