Can you imagine how he'd run against McCain in a general election? He'd put together an ad simply clipping those moments - and they're not rare - when McCain pauses, searches for words, blinks heavily and seems out of it. He'd play the age card as brutally as some Republicans play the race card. Then he'd put together a temper ad, throw in a little "bomb, bomb Iran" footage, and craft an LBJ daisy ad, raising fears about McCain's eagerness to start a nother war in the Middle East. I don't think Obama should go there, because I don't think he needs to and it would violate his core appeal. But others will. Check this out.
