Senator Thom Tillis publicly criticized Donald Trump for endorsing Ken Paxton over incumbent John Cornyn in the Texas Republican Senate primary, labeling the move a colossal mistake. Trump supported Paxton after Cornyn suggested the party move beyond Trump, leading Paxton to defeat Cornyn in the primary runoff. Tillis argued that Paxton's historical scandals and legal baggage have put a traditionally safe Republican seat at significant risk against Democratic nominee James Talarico. The intraparty dispute highlights growing friction between traditional establishment figures and Trump loyalists regarding candidate electability and strategic positioning heading into the upcoming midterm elections. National Republicans now face unexpected financial expenditures to defend a seat that otherwise would have remained secure.
