He had the luck of having a terrible inept opponent. With a good opponent, IMO he would have lost.
Not everyone who voted for Trump is crazy about him.
Yeah, and not everyone that voted for Reagan was crazy about him in '80. The first 2 years of Reagan sucked as a matter of fact. It wasn't until his policies kicked in that things started looking good. If Donny can follow through with his first 100 days crap, he will be in good shape.
As for another Rat beating Donny, just who was that going to be? OMalley? The Bern? Webb? Those are the three loser you have to choose from and 2 of them bailed before the first Primary vote was cast. That leaves the Bern, a Socialist loser who couldn't even beat Hitlary. There is no evidence that any Rat would have beaten the GOP candidate.
