Obviously, you have not read the article. Do not comment when you don’t know what you are talking about.
I read it, and it's an absurd arguement.
The distinction was there to allow someone like Alexander Hamilton, born outside the United States but present at ratification to be eligible. There's no indication at all of any intention to make ineligible individuals born in the United States to non citizens. As I'm sure you're aware, Martin Van Buren is widely credited with being the first American born President, being born to a former British subject after the revolution. A number of his successors would be ineligible under your rule, being born to former British subjects, and born after ratification. Including Abe Lincoln. Andrew Johnson's pop was likely born in England, though Andrew was born here.
It's an inane arguement which will go nowhere, but entertaing for those who can't find any policy issues on which to differ with BHO.
