Rapper Ludacris has been dissed big time by Barack Obama‘s campaign. 

Ludacris’ new track brags about Obama’s presidency being destiny but then uses an expletive to describe Hillary Clinton, calls President Bush "mentally handicapped " and that  Republican nom John McCain doesn’t belong in "any chair unless he’s paralyzed."

The rap doesn’t spare Jesse Jackson either.

"If you said it, then you meant it," Ludacris rapped.

Obama’s campaign flack Bill Burton tore into Ludacris’ "Politics As Usual" which appears on the mixtape Gangsta Grillz: The Preview.

"Rap lyrics today too often perpetuate misogyny, materialism, and degrading images," Burton said in a e-mail statement.

"While Ludacris is a talented individual he should be ashamed of these lyrics."

Ludacris’ publicist and manager did not respond to media queries.
