Meh, I dunno. She's wacky as hell and I dislike her a lot for being oversensitive about political correctness lately.
But she endorsed Rand Paul. Seriously, that's huge. I love it, and just for that I actually respect her just a little bit. In the end I love support for libertarians more than I dislike super-christian neo-cons that take unreasoned offense for something never directed to them.
As for her joining Fox. Meh. Doesn't surprise me. And Fox isn't much fair and balanced. They're fair and biased, just like any other news channel in USA. They're all flaming biased. Hehe.
