Here's a tip to Mitt Romney's ad team: Never begin an ad with any variation on the line, "Remember how our opponents accused Mitt Romney of killing a woman?" Your job is to make sure people don't remember that. And never close an ad by accusing your opponent of being willing to "say and do anything to stay in power." People like presidents who want their jobs, and don't just sit back and let people take their office from them. If you're going to accuse the president of doing something, accuse the president of doing something.

The middle fifteen seconds are pretty good, though.
