Obama stipulated to that well before the election, having made a nice pile off dreams of his dead, alcoholic, non-citizen father (as retold by the talented Billy Ayers). The sheeple elected him in full knowledge thereof. Therefore, it's the sheeple's fault!
Fact is, he's completely eligible, having been born in Honolulu. And no court is going to rule otherwise.
Actually, no court ruling during his current term would have any effect, anyway, given that impeachment is the only legal way to remove him (you need to enlist 67 senators). And it's a total time waste to maintain otherwise!
The issue is that his whole “persona” is fabricated, based on information regarding either his paternity or maternity.
