I thought this would be about his campaign message. Obviously the change theme won't work anymore, so hopefully he has some accomplishments to pitch.
"Four years ago, you voted for change. We've given you change...[insert various statistics]...But we aren't finished yet."
It probably won't be hard for him to take credit for the economy turning around and having gotten out of Iraq. I'd imagine it'd be more like:
"When George Bush was elected in 2000, we started losing jobs, we started losing our houses, we started losing wars, we started losing respect around the world. Now the economy has turned around, Iraq was sucessfully teminated, and we're world leaders again. Don't go back to the failures of Republican rule."
