Hey, I encourage this kind of thing. The more the better. It will wake up some people who have been blindly supporting the Democrats to just exactly who they are aligning themselves with. And those who approve of the ad are not Americans (or even recognizably human) anyway.
The primary is over, Kerry has a desperate need to appear moderate, and then his supporters go and do things like this. I'll bet his team has already asked the Nation not to run the ad.
I agree with you. They no longer feel the need for any restraint. They have the main stream media who are critical of the Bush campaign for dare showing a (proposed) ad in favor of Kerry that dispicts Bush as Hitler, but will give this a pass.
I say go for it. They are talking to themselves, and scaring middle America.
