That's good, you could be right -- "no Attainder of Treason shall work Corruption of Blood", is a specific that would override what I said re Benedict Arnold. Maybe. Probably -- would need to know what that term "Corruption of Blood" meant at the time, and it's really not that apt to Obama's case.

Also today I'm writing from what I remember of Blackstone, and I thought he had mentioned a consideration of treason. I could be wrong on that too. Still, the general point is that "natural born" is better read as "born to a natural presumption of whole allegiance".

The sins of the fathers.

Compare to:

"Fathers shall not be put to death for their children, nor children put to death for their fathers; each is to die for his own sins." [Deut. 24:16]
