This is Just Silly
The Clinton campaign produced this ad attacking Obama for not signing on to a debate in Wisconsin. Obama responded with this ad attacking the debate attack ad. Not to be out done, Clinton made a new ad, attacking the ad that attacked the original attack ad. And just today, the Obama campaign came out with yet another ad addressing the attacks in the new Clinton ad, which attacked Obama's ad attacking the original debate attack ad. We can only hope there are even more attack ads to come in this political equivalent of Russian nested dolls.
