Sen. John Cornyn watched with alarm when Beto O’Rourke nearly won Texas’ other Senate seat last year — alarmed that it could be him on the losing end when he’s up in 2020.
Determined not to get caught off guard by shifting demographics and fired-up Democrats, Cornyn is revving up his reelection campaign earlier than ever after O’Rourke’s near upset of Sen. Ted Cruz. Cornyn has already stockpiled more campaign cash than any other senator: $5.8 million. He’s filling high-level campaign jobs. And crucially, Cornyn secured early endorsements from Cruz and Lt. Gov. Dan Patrick, two of the most prominent conservatives in the state, in a show of force to prevent a primary challenge.
