Cruz WILL back whoever is elected as he gave his word.
Not sure the word of a lifetime politician and lawyer is worth much these days. Ted's not really a principled guy after all. The mask has fallen.
Cruz has shown himself to be untruthful a few times so far, why should he keep his word now?
Cruz will do whatever his masters, who own him, tell him to do. If they don’t have an opinion, he’ll do whatever is most politically expedient for his self-interests. His statement last night should have made that crystal clear (though we’ve known it for 15 years.)
