The House GOP released this video today, which is pretty effective. Barack Obama will almost always oblige a video editor by holding at least two transparently irreconcilable positions on a given issue, and stating them on camera (as I found when I was putting together campaign-era clips for my Obama vs. Obama video). Unfortunately, the voting public up until this point has almost always obliged him by believing he means whatever happens to be coming out of his mouth at a given moment. Polls show that's changing. Videos like this are a great way to whittle away at that power. One can only see so many times how naturally he contradicts himself before the mantle of new-politics reformer begins to look very unnatural upon his shoulders.
