I wonder what happens if its shown he is ineligible for Presidency, and rather than stepping down he engages a long drawn out legal battle.
On Jan. 20th 2009 Dick Cheney would be sworn in as acting President until the legal mess is settled. This could happen even if it gets settled, but doesn't allow sufficent time for transition, or for the remedy prescribed by the courts to be carried out.
Joe Biden becomes the president! Then Joe will pardon him for breaking the law!
If the U.S. Supreme Court rules Obama ineligible, he’ll never take the oath and will be wasting his own time (after he defrauded the American public). Today is the deadline for Obama to answer a “Writ of Certiorari” from Philip J. Berg and the U.S. Supreme Court.
