I've already said this on Twitter, but want to preserve this at the blog so that I can say "I told you so" in about two years.
My prediction is this: Within two years, Glenn Beck remakes himself as a David Brock/Arianna Huffington lefty 'disillusioned' with the right. He'll be so good at it that liberals will ... like him. Beck's left himself plenty of escape hatches along the way, with the "rodeo clown just trying to understand stuff" routine he does. He'll say: "Well, I understand now! And once Fox realized I was going places that weren't in line with GOP orthodoxy, they got rid of me!"
When I fall for this, I ask that one of you slap me. Hard.
