Obama can't run on change, or on economic achievements. So says a Vanderbilt political scientist in this report from The Associated Press:
"He can't run on change because he's the incumbent, and he can't paint too rosy a scenario because things aren't that rosy," said John Geer, professor of political science at Vanderbilt University. "He's got to come up with a theme that appeals to voters, especially middle-class voters, alleviates their fears and gives them reason to believe the future will be better."
In other words, we already got the change, and it sucks.
