The USSC does not want to deal with any of this because they are fearful of the political firestorm it would ignite. They are afraid the country can't handle the truth, at least at this time. Maybe later, when the administration is shown to be totally inept in both economic and foreign affairs, perhaps the Court will consider the matter further when it's less politically risky to do so.
Yes, this is possible. However, the SC need only agree to hear any of the many cases waiting to be brought before them to let this matter come to the public's attention and for the facts, such as they are, to be revealed.
While it is also possible that such a political firestorm could result or even civil unrest, we have survived both many times in our history.
If the facts are such that obama has perpetrated a lie against the country, there no doubt will be those who will not believe it and choose instead to believe it is all a republican conspiracy or a racial belief that the country isn't ready for a black man to be President (though obama isn't truly a "fully" black man) and "they" had to get obama.
I choose to believe if obama has perpetrated such a lie and it were to be revealed, the majority would see things for what they are and we would move forward. It might be ugly and perhaps bloody, but we would be better for having worked through it and sooner rather than later. Let's light that candle!
