The reason the current occupant of the WH is in there is that, despite the GOP leadership thinking he was unelectable, once they saw their base leaning that way they went all in, throwing the machinery of the party behind him. Admittedly this included techniques the Dems can't stoop to using, but that would apply to any GOP candidate.

Whichever candidate we end up with, we're going to hear ad nauseam that they are unelectable. So that is a red herring. We have to go "all in" just as they did.
