Ouch, that's not gonna help...

Well, at least Obama's ancestors didn't own Al Sharpton's ancestors.

Here's some sweet spin, though. Kudos to Bill Burton.

"Obama spokesman Bill Burton said the senator's ancestors 'are representative of America.' 'While a relative owned slaves, another fought for the Union in the Civil War,' Burton said. 'And it is a true measure of progress that the descendant of a slave owner would come to marry a student from Kenya and produce a son who would grow up to be a candidate for president of the United States.'"

Let's see if the 50% African-American constituency in the SC Dem primary buys the "progress of America" argument.
