Obama campaign criticizes Ludacris

There's a new celebrity tribute to Barack Obama, but his campaign isn't exactly loving it.

The rapper Ludacris has a video, titled "Obama is here," that predicts the Democrat will win the presidency and urges blacks to get out and vote. It features footage of Obama dancing on the "Ellen Degeneres Show" and shooting hoops with US soldiers.

All well and good.

The problem is that the video also disparages Hillary Clinton using the b-word and calling her "irrelevant" -- and mocks John McCain suggesting that he belongs in a wheelchair, not the White House.

"As Barack Obama has said many, many times in the past, rap lyrics today too often perpetuate misogyny, materialism, and degrading images that he doesn’t want his daughters or any children exposed to," Obama spokesman Bill Burton said in a statement today. "This song is not only outrageously offensive to Senator Clinton, Reverend Jackson, Senator McCain, and President Bush, it is offensive to all of us who are trying to raise our children with the values we hold dear. While Ludacris is a talented individual he should be ashamed of these lyrics."
