Barack Obama coasted to victory in Mississippi's Democratic primary Tuesday, latest in a string of racially polarized presidential contests across the Deep South and a final tune-up before next month's high-stakes race with Hillary Rodham Clinton in Pennsylvania.
Obama was winning roughly 90 percent of the black vote but only about one-quarter of the white vote, extending a pattern that carried him to victory in earlier primaries in South Carolina, Alabama, Georgia and Louisiana.
He picked up at least six Mississippi delegates to the Democratic National Convention, with 27 more to be awarded. He hoped for a win sizable enough to erase most if not all of Clinton's 11-delegate gain from last week, when she won three primaries.
Obama began the night with 1,579 delegates, to 1,473 for Clinton. It takes 2,025 to win the nomination.
