Yeah, but they have no enforcement powers. They can only hand down opinions.
Even if the Supreme Court had a unanimous decision that 0bama was not Constitutionally qualified to be President, who would actually enforce it? Certainly no one from the Bush Justice Department. There might be a few U.S Marshall's that would be be willing, but their bosses sure wouldn't. Joe Arpaio would have the guts, but D.C. is kind of out of his jurisdiction.
Bush himself? Declare martial law and demand a new election? Hardly. He's already got his bags packed and can't wait to get the heck out of office.
Congress intervene? HA! Not this Congress or the next one. Maybe a dozen of them would make some noises about it, but they would not follow through.
I know Obama won the election but he did not win in a landslide. I think there were many people who voted for him out of apathy, the so called historical aspect and because they liked the story about him and his family in People magazine. Not all are hardcore Obamabots. You don’t think there would be outrage if it is found out that he is ineligible? Our country would be so weak. What about our military? They don’t pledge an oath to the President, they pledge and oath to uphold the Constitution. Would you be able to support him knowing that he was ineligible? 58 million did not support him and I really believe of the 66 million that did, quite a few million would not just go along with him.
