Arianna Huffington's stripe changing?

I watch ABC's This Week round-table almost every week. (Personally I think Jake Tapper should get this show back.) I was just particularly amused by the round table where Arianna Huffington enveloped herself in a Jon Stewart blanket, without a hint of irony, denouncing demonizing in politics. She's apparently never read anything she's written in the past few years. Arianna was right-wing in the 1990's, left-wing in the 2000's, now she seems ready to embrace the Jon Stewart civility model. We'll see. But if she means it, good for her.
