This exact case is covered under the 20th Amendment. If Obama is not eligible, Biden becomes acting president.

I'm not sure if this is covered by the 20th Amendment which states "if the President elect shall have failed to qualify, then the Vice President elect shall act as President until a President shall have qualified;...". No matter what Obama has been calling himself, he is not yet the president elect; that will occur when the Electors cast their votes. Also, remember that the electors cast votes separately for President and VP. IF SCOTUS decides to rule, it could become quite interesting.

What the hell is the “Office of the President-Elect?”
