Seen the latest McCain commercial? The one that goes "Barack Obama is for higher taxes. John McCain is for workin' Joes." and so on, with monotonous (monorhythmic actually, it's just a beat) string music playing in the background. Take a closer listen to that music. Notice how all of the "McCain is for..." soundbites are set to lovely major chords whereas the "Obama is for..." bits have ugly dissonances in the background.

Could that be turned into an ad for Obama just by switching the consonant and dissonant chords? If I get my hands on that video I have to try it.
