Behind Obama's Big S.C. Win

Preview: Our story in the Sunday Post is headlined "Black Vote Vital, but Not the Whole Story." Obama was the overwhelming favorite among African American voters, and he picked up a quarter of white voters. As in previous contests, he did especially well among younger, better educated and wealthier voters. Obama also won three-quarters of "change-voters."

Half of white voters under 30 supported Obama, as did about a third of those with college degrees and those with family incomes of $100,000 or more. A breakdown of vote preferences among white voters is below, and an earlier version of the story from the exit poll is up now on The Trail.

There were fewer differences among black voters: Obama won both black men and black women by about 4 to 1, and had big margins among both younger and older African Americans. Complete exit poll data are available here.

UPDATE: The Sunday story is here, the accompanying graphic here. Other data from the exit poll went into S.C. analyses by the Post's Dan Balz, Anne E. Kornblut and Shalaigh Murray "Obama Is Big Winner in S.C. Primary," Jonathan Weisman "Edwards's Appeal Overshadowed by Rivals' Celebrity" and Alec MacGillis "A Margin That Will Be Hard To Marginalize."
