In the ‘immediate’ future it my well be impossible. That’s why we collectively need to elect people who have honor, integrity, huevos etc. that will ‘purify by fire’ (civilly speaking ;)the current judicial/political system and the cowards in it... and do EVERYTHING we can at EVERY opportunity to get people aware of what’s really going on under their noses.
But if no relevant new facts come up, no court is going to bring in a new interpretation that unseats a president and overturns an election. Voters knew going into the election that Obama's father was Kenyan and could have found out that he wasn't a citizen. Justice Roberts knew it when he swore Obama in. Given all that the natural born citizen theory isn't going anywhere.
Not so long ago there were lawsuits to the effect that Bush and Cheney couldn't be president and vice president because they were "really" from the same state. No court was going to take that case and unseat an elected president because of a difference in interpretations, and the Supreme Court isn't going to take the natural born citizen case now and kick Obama out.
