Texas Attorney General Ken Paxton recently declared his intention to challenge incumbent Senator John Cornyn in the 2026 Senate primary. This announcement marks a significant development in Texas politics, as both figures are prominent in the state. Paxton framed his candidacy as a means of bolstering support for former President Donald Trump within the Senate.

In his announcement, Paxton emphasized his desire for a senator who would strongly advocate for Republican values, the interests of Texans, and support Donald Trump. He highlighted the need for a senator who would actively defend Trump's agenda.

Paxton's campaign is expected to focus on criticizing Cornyn's past reservations about Trump and his policies. Cornyn's past statements, such as his skepticism about a comprehensive border wall, are likely to be points of contention.

Cornyn's voting record and stances on key issues, such as the Bipartisan Safer Communities Act, are also expected to be scrutinized. The Act, which expanded the government's ability to restrict firearm purchases, drew criticism from some Republicans and gun rights advocates. Cornyn defended the bill, asserting its focus on keeping guns out of the hands of individuals with criminal backgrounds or mental health issues.
