CHICAGO (Reuters) - Barack Obama's approval ratings are down, Republican challengers are beating him in polls and the U.S. economy is in a slump, yet the Democratic president's re-election campaign headquarters is buzzing.

It sounds like a nice sentence, but a bit of supporting evidence would help, especially considering he's leading in the latest AP-KfP polls against his republican challengers.
