Exactly the point, and the same one Spaulding makes up thread (and I and many others have made for a long time now). In the case of Chester Arthur, the B.C. was made the issue (albeit, not as big an issue comparatively to Barry's) instead of his born with foreign citizenship.
Generally speaking, it's much easier for people who don't know the history during the founding era to make a decision for themselves weather or not Barry is eligible...if he was in fact born in another country.
What many American's don't realize, is that the framers put the NBC requirement in to prevent (as best as possible) someone who themselves were born with foreign allegiance owed becoming the Commander in Chief of the (then) army and navy and the head of the executive branch who enters into dealings and agreements with foreign heads of state (conflict of interest).
It's really a national security/sovereignty issue at it's core.
Chet got away with it. IMO, that is what gave BHO, Jr.'s team the nerve to try it. In fact, until last year, when Attorney Donofrio inspired the research, it wasn't proven that Chet had lied about his origins. 125 years!
Thanks to the internet-inspired revolt, we'll prove that Obama lied in 5!
Bingo! (And THANK YOU very much for all of the illuminating research and posts that you have provided for us on this vital issue!)
