Samuel L. Jackson and Barack Obama may have a certain amount of preternatural cool in common, but there's one thing Jackson can do that the presidential candidate can't: curse up a storm! While promoting his new film Soul Men, the actor opined at length on all things Obama, and thanks to Hollywood Outbreak, we have the NSFW audio (caution: as though he were back on the set of a Tarantino film, Jackson lets fly with a torrent of "n-words").You may be interested to hear Jackson hold court on Sarah Palin rallies, how Obama is hamstrung by what society wants to see in a black man, and his greatest fear involving the candidate, but our favorite moment was Jackson's brief, jowly McCain impression. Hey Sam, we hear SNL is hiring — sure, there's that whole racial barrier thing, but that hasn't stopped Fred Armisen from playing Obama, has it?
