In New Jersey with its huge population on New Yorkers your not going to see them voting for Cruz.
Christie isn’t half as popular as Trump. In fact I can say Trump wins NJ, PA, CT and NY primaries. And puts them into play for the general election. Even MA. is potential for a big upset a blue state going for Trump.
I don’t see Cruz getting a win in the General in any place not a deep red state. Cruz can’t move to the center, Cruzers would abandon him.
Palin has been mentioned by Trump as someone he wants in a Trump administration.
Palin all but said she would serve with him. Trump has said lots of times very very high praise for Sarah.
I think Sarah endorses Trump in SC. if his polls look like he has the potential to run the table. I think Palin usually is a King maker, but she want to jump on board early on and ensure she gets of credit for her endorsement.
I agree its too early for her, but anyone wanting more evangelicals and Tea Party voters would love her endorsement. People do what she tells them.
