If it’s discovered that he is ineligible to be president, at this point, it’s too late. We can’t undo the last four years. He got his time in and the damage is done.
Actually I think it would be cheaper to disregard all the laws Obama wrote in at a loss than to try and prop them up any further. Thats the problem with a communist structure, costs too much to enforce, and the moment when you fail to keep up the fear and threats the people tear down your walls.
All the legislation that Obama signed and all the Judges and Justices he appointed are null and void.
