Trump's trade war could cost him Texas and the presidency

As Senate Republicans wait on tenterhooks for Vice President Mike Pence to talk trade with Mexico’s foreign minister, a new Quinnipiac poll should have the entire party shaking in its boots right now.

Sen. John Cornyn, R-Texas, who’s up for reelection, can feel pretty secure in his incumbency. His net approval rating is in the double digits, and Beto O’Rourke, favored by Texas Democrats to abandon his doomed presidential bid in favor of challenging the Senate seat, seems unlikely to jump ship.
