I look at it more as a function of choosing platforms. Romney and a host of others are trans-nationalists, they will always object to a nationalist platform. The split exists and cannot be reconciled. No hard feelings, one side or the other will get the levers of power.
I see the split as a good thing, and so does Trump. he does not think uniting the current membership of the party is necessary
He says in 2012 as a businessman he is not looking to get in a fight with a politician, he wants to get along with them, of course he won't be critical. Says Hillary has in fact not done a good job, look at Libya, Benghazi.
Chuck Todd wants the tax returns. Trumps pledges to release them when the audit concludes. Hahahah. That puts Obama in a box, does he want to use the IRS to go after Trump, or not?
What is so sad is that people we revered,trusted and listened to intensely; Rush Levin, Beck others have lost all credibility on their shows.They will now spend the rest of their broadcast careers trying to get their lost credibility back.
It interesting that what you are seeing in Trump is a return to an American 1st Foreign Policy for the 1st time since Reagan. No surprise the Internationalist lead by the Bush Family are afraid of seeing their 40 years of work corrupting the GOP undone by a Trump Administration,
