A repub friend of mine sent me the link and I dont know if its an internet ad or a tv ad as well, but my point is that its pretty darn effective.

The ad starts with a video of Kerry saying he has not used negative ads on his opponents. Then a couple of statistics say how many negative ads he has used. The ad also uses visual techniques that I think are very effective at persuading or just brainwashing people. If fierce attack ads like this keep coming from the Bush-Cheney camp we might as well see Bush cruising to reelection in November, unless Kerry counterattacks with fierce ads of his own.
