Here's what I'd like to see:
Obama: "I know there has been a lot of confusion about how my health care plan works, so here is someone who can explain it:"
40" Video of Romney explaining how his "personal responsibility" Massachusetts health care plan works
As Romey talks, show pictures of him signing the legislation, speaking about it, the framed copy of it on his Governor's desk, etc.
Follow this with a clip of Romney saying his MA plan should be a model for the nation.
Obama: "I'm Barack Obama and I approve this message"
This ad would serve to:
1. remind everyone what a hypocrite/fraud Romney is.
2. remind the Republican base why they don't like Romney, thus dampening their enthusiasm.
3. sway those in the middle who still aren't sure what to think about the health care plan.
