Paxton defeats Cornyn in the Texas Senate runoff despite a 17-to-1 spending deficit

Ken Paxton defeated incumbent Senator John Cornyn in the Texas Republican Senate runoff, winning approximately 57 percent of the vote despite being outspent 17-to-1 in the runoff alone. Cornyn spent more than $50 million in the runoff to Paxton's roughly $3 million, yet lost by a double-digit margin. The result ended Cornyn's 24-year Senate career and marked the first time a sitting senator with a leadership-tier record had been defeated in a primary by a Trump-endorsed challenger.
