The 2026 political landscape is heating up, and Texas is at the center of the action. Attorney General Ken Paxton has publicly expressed his interest in challenging incumbent Senator John Cornyn for his seat, setting the stage for a potentially explosive Republican primary battle.

During a recent address to Republican constituents in Denton County, Paxton didn't mince words, calling out several Republicans he deems insufficiently conservative, including Cornyn. His suggestion of replacing the senior senator was met with enthusiastic applause, further fueling speculation about his intentions.

Paxton, a staunch ally of former President Trump, has been critical of Cornyn's record, questioning his accomplishments for Texas and the nation. His past comments, including a September 2023 interview where he stated "everything’s on the table," have hinted at a potential Senate bid. He's now actively engaging with various groups within Texas, exploring the viability of a 2026 campaign, with a decision expected in the coming months.

Paxton's criticisms of Cornyn paint him as out of touch with Texan conservative values and insufficiently aligned with Trump. He's frequently used the label "RINO" (Republican in name only) to describe Cornyn, a term often employed by MAGA and "America First" Republicans against more establishment figures within the GOP.

Sources close to Paxton indicate he's actively assessing the situation, planning meetings with voters, donors, and activists across Texas to gauge support and determine the best way to serve the state.

Paxton's political journey hasn't been without its challenges. He overcame a primary challenge from George P. Bush in 2022 amidst accusations of bribery and corruption. He was later impeached by the Texas House of Representatives in 2023 but ultimately acquitted by the state Senate.

Cornyn, a seasoned politician with a long Senate tenure dating back to 2002, has held key leadership roles, including chair of the National Republican Senatorial Committee and Senate majority whip. Despite an unsuccessful bid for Senate majority leader in 2024, he has affirmed his intention to seek re-election in 2026.

Cornyn has been a vocal supporter of Trump's Cabinet appointments and has criticized Democrats for obstructing confirmation processes. This stance further complicates the potential primary battle, raising the question of whether Trump would endorse Paxton or back the established GOP figure.

Political analysts, like Matt Mackowiak, a Republican strategist, acknowledge the potential significance of a Paxton-Cornyn primary clash. He notes Cornyn's undefeated electoral record and strong statewide support, while also recognizing Paxton's chances. The potential race is described as a potential bellwether with national implications, drawing in activists and resources from across the country. It's likely to be months before the situation fully unfolds.
