The Democratic National Committee is promoting an upcoming rally for President Obama by sending out a blog that touts the musical act preceding him as "f---ing awesome."

A DNC spokesman blasted out an e-mail alert Monday that included a post from the Philadelphia City Paper's website. The paper reported that hometown heroes The Roots would be performing at Obama's Oct. 10 rally in Philadelphia.

"You heard it here first: Just got word from a Democratic source that The Roots, who campaigned for Obama in 2008 and are f---ing awesome, will perform next Sunday as part of President Obama's Move America Forward Rally," the City Paper reported without editing the explicit language.

The president is holding the rallies to build support for the Democratic agenda and drive up turnout in the upcoming congressional elections. The White House snagged Obama supporter Ben Harper to perform at the last rally in Madison, Wis.
