You said you'd "take it back" if people provided evidence of a single Republican slaveowner in 1860. Take it back.
According to the US slave schedule of 1860, Blair owned slaves.
According to the Republican convention of 1860, Blair was a delegate there.
So, @DineshDSouza, take it back.
Hard to argue with that.
Looking forward to Dinesh taking back his claim that there were no Republican slaveowners in 1860, as he is surely a man of his wor-- dammit, I almost made it without laughing.
