First Romney is held to account for his great-great-great grandfather's actions now Obama is being held to account for this. I think both stories have Clinton fingerprints all over them. And this from the couple who believe that they can't be held responsible for what they did 10 seconds ago. They are a contaminant to the body politic of this country.
If we wanted to tar a candidate with slave ownership or polyagamy, we don't need to go that far back. Obama's own father was married to another woman when he married his mother and he later took a third wife. I'm sure his black muslim father or a not too distant ancestor probably owned slaves, also, as muslims do not consider slavery wrong.
