In that case he would have been a citizen at birth, and no need for all this run around with the BC. If that were revealed, it would change nothing. He's have been a citizen at birth, but rather than one with a foreign citizen father, he'd be a bastard citizen at birth. Subtly different of course, since he would not have the problem of a foreign citizen father, but would have the problem of not being born on US territory.
He would however not fit the Constitutional eligibilty as a natural born citizen. I want that damned Constitution to mean something, and this lying commie freak is pissing upon it and laughing at the dead republic he has succeeded in slaying. If the federal oligarchs can deny We Te People standing to challenge this fecal Chicago floater, then the Constitutional contract is no longer in force, abrogated by the federal oligarchs now paddling the canoe down the sewer.
