Genteel Republicans like Mitt Romney complain about Donald Trump’s unpresidential behavior, but how else does he combat the dirty left? Only a barbarian could defy the liberal establishment as he has done. Imagine if Romney were president, trying to be dignified and patrician. They’d eat him alive. Unless, of course, he did nothing to block their agenda, in which case he’d be left alone like all the other cowardly roll-over Republicans.
