They realize that nobody likes their dinosaurs like Kasich or Rube-o, so they switched to someone who had a history of actual conservatism. Too bad Cruz is willing to give up his record and start appeasing GOP-e vermin just to win the nomination this year.
If Cruz didn’t try to backstab Trump, he almost certainly would have won the nomination in 2020 or 2024. Now his political career will likely never advance beyond Senator, and his soul is likely on the path to eternal damnation.
Cruz has a “history” of conservative speeches.
