Cruz wants to run in 2020, he won’t be supporting Trump.
No doubt - but if he can't do the right thing now and act like a man who puts the Nation above himself, he will be a has-been that could've been by 2020. He's working with the enemy for personal gain and is not the conservative champion of the People he tried to portray himself as.
As far as I'm concerned, he's not half the man Trump is and will never get there.
