This is all tilting at windmills anyway. There's no way at all that Obama is going to be removed from office over this.
The people who supported him are the sort who believe that it's OK to lie, as long as the lie you're telling advances their political agenda, or conveys how things "should" have happened.
These are the same sort of people who, when PETA couldn't find any cooperative baby-seal-clubbers, for to film the horror of the thing, clubbed some baby seals to death themselves, so PETA would have something to film.
Truth doesn't matter to these people. Fact doesn't matter to them, either. The vision matters; the agenda matters, and when reality gets in the way of it, reality is ignored.
Obama could come out and say, under oath, "I was born in Pakistan, and my parents, in a bizarre love triangle, were Osama bin Laden, Fidel Castro, and a small furry creature from Alpha Centauri", and the people backing him would still dismiss any claims against his legitimacy as "racism" or "right-wing extremism", and continue to back him, because he's their current Messiah.
Even if he's proven to be ineligible for the presidency, I don't see him being removed from office before serving a full term. People might not vote him in again, but no one in the political power structure has the big brass balls, and the clout, and the desire, combined, to pull him out of office.
