Speaker of the House Ryan just stated on the news he can’t support Trump yet....he wants to support the nominee but not yet at this point because of the republican platform that unifies all needs to be presented by Trump...
We need a standard barrier who will unify all the party and the nominee needs to do that. Can Trump turn this around and unite the party???
If he turns tail on the wall he loses his base of support.
Short answer, no. Irreconcilable differences .
