Clear as mud. Paine only says that the President is never a foreigner. Not a half-foreigner, a foreigner. And nobody disputes that. The President is a natural born citizen and not foreign born.
Your attempt to sow doubt as to what I can clearly read is futile. I admit that there is strong evidence on the other side, but if your goal is perfect refutation of all opposing views (the liberal MO, BTW) then give it up. Just chalk this one point up for Paine, and move on.
