Cruz tipped his hand in the post-debate interview with Jake Tapper, where he spoke about his "friend" Marco and how they were both more qualified to be President than Trump. He also mentioned that he had spoken to Jeb a few days before to tell him that he would be missed by him because Jeb and him were the only ones who would stand up to Trump. It starts at the 4 minute mark.
If there is a brokered convention, you can expect Cruz to work with the GOPe.
With or without, they are his only backstop. Trump has no need or use for him, no deals to be made there.
I think Cruz and Rubio are still independent, each clawing for their own self-interest. That picture will clear up in a couple weeks. I think the big picture is lineup is MOST Senators and MOST governors line up anti-Trump, and a few senators (maybe just Sessions) and a few governors (Christie, Brewer, LePage) line up behind Trump. I think that pretty much reflects the split in the party, the Trump insurgency is minority "within the fort." What is carrying Trump is almost entirely public popularity in defiance to the party. Long overdue, so happy to see it happening.
Yeah, I think the GOPe’s fear and loathing against Cruz is overblown. Cruz is a solid conservative Republican, campaigns tirelessly, and will certainly work with the party to destroy Hellary.
