Hilary = 1984 video
So everyone is denying knowing anything about this ad. That's the beauty of the Internet Age... plausible deniability. Of course the candidates aren't going to know about stuff like this, it lets them keep their hands clean while "independent" mudslingers do the dirty work.
You know, maybe I'm Machiavellian, but I wouldn't be surprised if this originated from Clinton's "camp" just to make Obama look bad. Think about it... who does this ad make look worst? Sure, it's a jab at Hillary, but it's just imagery with no substance. It's like taking a punch just so that you can charge the other guy with assault.
Maybe it's good that I'm not in politics.
