Should BHO win 2012 (shudder) and after the election it is proved he is not a natural born citizen, would his EO’s and other machinations in office become null and void?
If Obama wins in 2012 and even it's proven he was born in Kenya. He's not going anywhere. In fact, given his record, he may be President beyond his second term.
Obama could be born in Kenya and have ties to Al Qaeda. He's not going anywhere. It's going to be very difficult to rid this nation of him even after 2016 IMHO
