Obama, Thompson take lead in South Carolina

African-America support has pushed Barack Obama in front of Hillary Clinton, 34% to 25%, in the latest Mason-Dixon poll in South Carolina. John Edwards is in third with 12%, and 24% of respondents are undecided. (Maybe they're going to break for Mike Gravel! Don't laugh... haven't you seen his new avant-garde campaign ad?
'Nuff said.)

Meanwhile, Fred Thompson has taken the lead on the Republican side, leading Rudy Giuliani 25% to 21%, despite the fact that he has yet to officially declare his candidacy. Mitt Romney is third with 11%. McCain really does look like he's finished, polling a paltry 7%.
