Conservatives have been rightly disappointed to the point of disgust with establishment Republicans (Dole, the Bushes, Romney, McCain), so they grasp at any straw they see. Usually, that straw is some fringe, self-promoting clown who happens to mouth the right rhetoric for the moment. They're dreaming of a conservative Great White Hope to come along and drive out the GOP establishment. It's a worthy dream, but I have news for them: Donald Trump isn't it. Like all self-promoters, his political "positions" are those that draw the most attention and controversy at the moment.
When people support hard liberals 2 elections running and then offer support for yet another, I don’t know that does not make the people doing hard libs themselves if words and actions mean anything at all.
