President Donald Trump endorsed Ken Paxton in the Texas Republican Senate runoff, giving Paxton a high-profile boost against incumbent John Cornyn. The endorsement drew competing reactions and intensified concerns among Republican leaders about the party’s chances in November.
Trump endorsed Paxton on social media during a Paxton campaign event in Allen, Texas. Paxton thanked Trump, while Cornyn said the endorsement would affect the race but vowed to keep campaigning. The two candidates advanced to a May 26 runoff after finishing as the top vote-getters in the March 3 primary.
The article reports that Cornyn’s campaign and allied groups had spent substantially more on advertising than Paxton’s, and that Republican leaders worried a Paxton nomination could require greater spending to defend the seat. Democratic state Rep. James Talarico said the Democratic candidate would face the political system rather than either runoff candidate.
