Texas Attorney General Ken Paxton is intensifying his campaign against incumbent Senator John Cornyn in the 2026 Republican primary. Paxton, a prominent conservative figure, announced his Senate bid this week, setting up a high-profile contest that could reshape Texas politics.

Paxton's decision to challenge Cornyn comes after years of tension between the two Republicans. The Texas attorney general has positioned himself as a more hardline conservative, criticizing Cornyn's willingness to work across the aisle on certain issues. This primary battle could test the direction of the Texas Republican Party.

Cornyn, who has served in the Senate since 2002, holds significant institutional advantages and a strong fundraising base. However, Paxton's aggressive campaign style and loyal conservative following make him a formidable opponent. The race will likely focus on key issues like border security, federal spending, and the future of the Republican Party in Texas.
