Why can't the fact that Trump has shown that Republicans and conservatives, despite their reputation and public bravado, do not actually possess the courage of their convictions ever work to the advantage of Democrats and progressives?
For conservative Christians, "character" is what mattered. Until it didn't.
For Republican hawks, Russia was the enemy, until it wasn't.
For almost all of them, Wikileaks was traitorous, until they weren't.
It goes on and on.
So if Trump were come out and say, "I think Universal Health Care makes the most economic sense. Let's let GM focus on making cars, not on healthcare," who's to say that his base wouldn't just follow along?
They'll follow Trump anywhere, so why can't it be somewhere good?
