The video that changed an election campaign. It's a video that still affects me. Mock it all you want. Mock me all you want. There is a reason this ad resonated. It has to do with eight long years of shame and drift and failure. It's a statement that Bush and Cheney are not who we are. They are not the America that has existed and will one day be regained. The stain of these dark years - years of torture and intolerance and fear and raw power - can be erased. But only one candidate can start that process. And only we can finish it:

We are the change we've been waiting for.
