I wonder how long it will take for them to figure out that his father's muslim ancestors sold those slaves.
By the time of the American Revolution there were just under 2.5 million.
However, Obama's white ancestry runs all the way back to the early 1600s (actually 1598 in Bar Harbor Maine), and there were at most a few hundred Europeans roaming around in that territory at that time.
I would suppose that by 1619 most of them owned one or more black slaves, that having become the fashionable thing to do hereabouts.
It's really, really difficult to have early American ancestry and not to have a slave-owner in the line, or, as it turns out, a slave as well. It's fairly easy to find an Indian or two, and this one Jewish woman the authorities didn't think was fit to be landed in Manhattan, so they ran her all the way up to Shodak Island. She's pretty much the mother of her country.
I'm not judging those people and I expect you people to not do so either!
