Cruz hasn’t betrayed conservatives.
Cruz betrayed Canada!
I guess you are good with the Corker Bill which allowed Iran to keep their nuke stuff and we paid them $150B to boot, or maybe you are good with TPA for Obama. Cruz voted for cloture on that. I do not remember Cruz promising to give Obama more power by abrogating the treaty clause of the constitution when he ran for the Senate but he did do it. Twice. He also wanted to increase legal immigration and expand H1B visas 5x until Trump being in the race forced him to change. I expect stuff like this from Cornyn, not Cruz. I call those things a betrayal, but if you are good with them, more power to you.
