Reince Priebus deserves an Oscar for the roll he played as RNC Chairman. He was as important to the Trump campaign, as Chairman, as was Steve Bannon. But, Priebus is not a "rough and tumble" sort of guy. He is in the company of a group of political butt kickers . . . . . a little out of his element.
Nothing wrong with Reince. Nothing wrong the political butt kicking mentality. But the two do not make for a good marriage. If he stays, he stays. He is fiercely loyal to the President, but is no match for the Posse that rode into town with Trump.
