Personally, I suspect that even if we could prove that the President was not Constitutionally eligible, it would be a moot point. I remain agnostic on the matter of O’s eligibility... I really do not know if he’s a natural-born citizen or not... but I also believe that the right has already lost on this issue. It’ll be like that Dem senator said about Clinton, to the effect of “I don’t care if you have videotape of him murdering somone, we’re not going to convict him.”
Barry doesn't necessarily need to be convicted by the Senate. Nixon resigned after the House passage of allegations (impeached). And, it was 2+ years before SCOTUS ordered the release of the Watergate tapes which then caused a "lack of confidence" within the Senate. Nixon, of course, resigned before he was "convicted."
If enough of the country is aware Barry is a usurper, there's little doubt he'd retain the confidence of anyone in Congress except the far left (Pelosi, Reed, Waxman, etc). I can't imagine the joint chiefs of staff would continue to honor any "order" coming from a usurper. Barry can be "forced" to resign.
“I really do not know if hes a natural-born citizen or not...”
Maybe this could help you out???
