Sen. John Cornyn’s uphill battle for renomination from his party reaches its conclusion Tuesday. Cornyn’s race against state Attorney General Ken Paxton was considered highly competitive until a week ago, when President Donald Trump abruptly backed Paxton and made him the front-runner for the nomination. Cornyn has refused to drop out and is still fighting through Tuesday, arguing a Paxton nomination puts Republicans at risk of losing his seat in November. Plus, there are several other notable races on Tuesday’s ballot to watch. At stake are the political futures of three Democratic members of the House as well as the direction of one of the most consequential statewide offices.
