Well?....There are two ways to pluck a duck: In the courts and Public Pressure.
Since I am not an attorney, I can't comment on whether or not there will be legal success in getting Obama to disclose documents.
However...If it weren't for the publicity generated by Taitz, Berg, and the other lawsuits, few in our nation would even know that Obama had a problem with natural born citizenship.
In the best case scenario, Obama will be revealed. He will be arrested for massive fraud, and be put in prison for a long time. I doubt that he would be turned over to a military tribunal and tried and executed for treason.
A likely scenario is that he will not run in 2012, and for evermore all candidates for president and vice president will be under state law and public pressure to prove their natural born citizenship.
More speculative scenario for those with their heads in the sand???
