It always confounded me why the Right embraced this guy. He's always been an opportunist and a drunk. Not surprising that he's anti-Israel when he's been quoted as describing the Old Testament as "..a bunch of bloodthirsty nonsense". More recently he publicly debated George Galloway, but only as part of a jointly-run PR blitz for their respective book tours.
In short, I'm not at all surprised at this latest stunt - it gets his name in the press afterall...
