I just came across this video on YouTube posted by OpenSourcePundits.  
All clips from Obama, McCain, RNC, DNC youtube channels. Also using an ad by Senate candidate Scott Kleeb, and a photo taken by Jill Greenburg.

Music by Straylight Run, "First of this Century" on the album "The Needles the Space".

Additional plug: check out the WBEZ radio program "This American Life" for the program "The Enforcer."
Enjoy, o weary Change Agents!
