OBAMA: After they drove the car into the ditch, made it as difficult as possible for us to pull it back, now they want to keys back. No! You can’t drive! We don’t want to have to go back into the ditch. We just got the car out.

Jon Chaitt adds:

I think we can see his main political theme for 2010 and 2012 taking shape here: Republicans screwed the country up, Obama got to work fixing it, Republicans took an ultra-partisan stance on every issue, and if you give them power they'll screw things up again. It's quite simple, and has the added virtue of being true.
