I've yet to see Ariana Huffington do anything more than try to make the good and decent outspoken critics of the US Government seem as shrill as she is.
I don't necessarily agree with everything Clooney's said, but the man actually puts thought behind what he's said, and for that, I can respect it. Huffington has consistently used simple attack methods. I couldn't even tell you half of her political views because she's simply anti-everything. A horrible view of the left side of the argument.
