Two man race, for sure.
Cruz’ margin is Idaho is larger than Trump’s in MS or MI.
Trump called it, "Little Marco."
Having said that...Marco would still be a far better choice than Hillary or Sanders.
But it is just not going to happen and whether he is willing to admit it or not...it was his willful decision to renig on his campaign commitments and join in with the gang of eight that did it to him.

He can only go to heavily red caucus states.
OR rely on the Rubio-Katich tag-team to hold Trump down enough that Cruz makes it "look" close.
The missing element in the calculus,is how many of those voting "really" want their guy to win, vs. how many GOP-e lackeys spitefully trying to deny Trump what is by now obviously rightfully his.
Any normal, honest, non-corrupt human would have dropped out by now if they were Rubio or Kasich: what % do either of them have to pull, from here on out, to win the nomination?
