I think we have to ask ourselves as a nation if we want a President who can't be loyal to his/her political party. If we can't trust Donald Trump to be loyal to the Republican Party, how can we expect him to be loyal to the country? He claims he's "loyal to a fault" but look at his marriages, look at how he is treating people who he previously supported - namely Rand Paul - in this campaign. Now this.
Uh, since when has a candidate campaigned on party loyalty in a general election? I don't recall Romney going around in the general saying, "hey look, I'm a good republican. I always agree with Republicans."
