You are in the minority and for good reason. Mitt Romney is an opportunistic snake. A liar and a turncoat. He signed the pledge and reneged. He lied for 45 minutes on major network TV about the Donald. And, did irreparable damage. Trump won in spite of his sabotage.
Anyone who would support him is a moron or a masochist.
And these personal loyalty spats appear to be much less important to Trump than to his cultists.
I think Trump will do fine. The country is more important than fealty to one man and that's how Trump seems to be approaching his appointments no matter how you feel about it.
