There's nothing particularly fringey about me, at least not politically. I would have been a Democrat 20 years ago. Now-a-days, I'm too liberal to be a Democrat - most Democrats are right-leaning moderates. This can be demonstrated on any political spectrum. Quite a few of them have been plotted. Even Obama, one of the more liberal Democrats of today, is only very slightly left. He's definitely not liberal.
Things like taking all the teeth out of FDA and EPA, essentially scrapping public ed, gutting Medicare, etc, didn't used to be a viable platform even for a Republican. Bog standard conservatism is a stance of continuity. Far-right conservatism is regressivism. Huntsman is plainly regressive in quite a number of issues.
Al Gore actually has a fairly good quote on this. His stances really haven't changed much since the 90's. Back then, he was a Democrat. Maybe *slightly* more liberal than most, but not substantially. Not he's considered a whacko communist. On this, he says, "My position hasn't changed. The scale has moved right."
It's hard to deny that there's been a swing to the right lately. The beginnings of it go back to the 70's, but it didn't become a popular movement until the turn of the millennium.
