John McCain "Don't know much" about the economy

Obama's newest ad:


It's okay, but I agree with Josh Orton:

It uses the infectious riff from Sam Cooke's classic "Wonderful World," but is it too cute? McCain's ignorance of economics is dangerous - why give the impression that the problem is benign? And why not use McCain's quote about the economy's supposed "strength?"

Maybe this will catch on. The song sure gets stuck in your head.
