Not all rappers are dumb as doorknobs. Rapper Ludacris, real name Chris Bridges, knew exactly what he was doing when he called Sen. Hillary Clinton the B-word on his new track in support of Democratic presidential hopeful Barack Obama.

“Hillary hated on you, so that bitch is irrelevant,” declared Luda on the track titled “Politics: Obama is Here” As you can imagine, the track is causing quite a commotion in the offices with the high glass ceilings.

Obama’s camp was swift to denounce the lyrics contained in the song. But Luda knew that would happen. I’m sure he counted on the media to jump all over the lyrics — which they did. Mind you, these are the same misogynistic lyrics rappers have been using to describe their Nubian sisters for at least 3 decades.

“I hope Senator Obama has the presence of mind to denounce and distance himself from Ludacris,” Sen. Clinton’s former national finance co-chair, Yashar Hedayat wrote in an email to the Huffington Post.

Obama campaign spokesman Bill Burton released a tersely worded statement condemning Ludacris and all rappers like him who use offensive language under the guise of “artistic expression”:

“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. 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.”

Ashamed? No. Paid? Yes. After all, who cares about mothers and children when it comes to the pursuit of the almighty dollar.

Oh, and expect Luda’s publicist to issue a carefully worded prepared statement apologizing for his “unintended” offensive lyrics in 5…4….3…2…
