With polls showing parts of the Democratic base apathetic about the midterm elections, President Obama urged his supporters to rekindle their enthusiasm and vote in November.

"It will be up to each of you to make sure that the young people, African Americans, Latinos, and women, who powered our victory in 2008 stand together once again," he said in a video released Monday.

Foreshadowing his likely 2010 stump speech, the president warned that a cadre of "special interests" were looking to "undo all that we have accomplished."
