Obama leads in S. Carolina but racial gap widens

While his edge his closer than in some other polls, Obama leads Hillary in South Carolina, "where their increasingly bitter rivalry has opened a deep racial divide among Democrats days before the party's first primary in the South on Saturday," McClatchy reports tonight in reviewing its new McClatchy-MSNBC poll. African-Americans break solidly for Obama, with 59 percent supporting him vs. 25 percent for Clinton, 4 percent for former North Carolina Sen. John Edwards and 12 percent undecided. White voters: 40 percent support Edwards, 36 percent back Clinton, 10 percent are behind Obama and 14 percent are undecided.
