Texas Attorney General Ken Paxton blew out longtime Senator John Cornyn by nearly 30 points in the Republican primary, a result that hurts establishment Republicans and gives Democrats a real shot at the seat.

• Cornyn, a hawkish, country-club Republican, got crushed despite outspending Paxton nine to one, with Trump's late endorsement sealing it.
• This is the second sitting Republican senator forced out in 10 days, after Bill Cassidy in Louisiana, signaling Trump now fully owns the GOP base.
• Democrat James Talarico will face Paxton, who is loaded with baggage: an impeachment by his own party, an adultery scandal, bribery and fraud accusations, and a mug shot.
• Texas now moves from safe Republican to in-play, joining North Carolina, Maine, and Alaska as possible Democratic flips as the Senate map tightens.
• Trump's primary endorsement record is now 9-0 for Senate, 8-0 for governors, and 101-0 for House, showing no Republican survives crossing him, as Chip Roy also learned by losing his primary.

Outlook: Texas is set for the most expensive Senate race ever, and Democrats have a narrow but real path to flipping the seat if Paxton's scandals stick with moderate voters.
