Lol I'd bet those that end up voting Cruz or Trump probably did vote for McCain and/or Romney. After all, you just said you voted for McCain lol. Lol I'd think if they didn't like the establishment they would not vote for a Democrat or a Republican. It's like the tea partiers and the libertarians and how they pretend they aren't establishment and yet they join a 150+ year old establishment party. Lol as for saying conservatives didn't turn out, that's a joke, voter turnout in the past two general elections was record breaking.
I don't think McCain is a fake conservative, that's ludicrous, he's one of the oldest serving GOPers and has a pretty consistent record of voting along GOP lines. As for Mitt, I didn't like him from get-go, no trust for a mormon. Same reason why I won't have Carson, no trust for the SDA cult.
Trump intrigues me though, I don't think Trump is a conservative, I don't think he's a leftist either. Trump got that king mentality. Could be a good thing, could be a bad thing, we'll find out soon.
