US Senator John Cornyn and Texas Attorney General Ken Paxton are headed to a Republican runoff after neither was projected to win more than 50% of the vote in the Republican primary. Cornyn was leading in the three-way Senate primary, with U.S. Representative Wesley Hunt trailing in third place. The two will face each other in a May 26 runoff. Allies of Cornyn, who is backed by Senate Republican leaders, spent over $60 million to boost his chances. However, critics argue that Paxton's history of scandal could jeopardize Republicans' safe Senate seat.
