Amendment 20 Section 3
...;and the Congress may by law provide for the case wherein neither a President-elect nor a Vice President elect shall have qualified, declaring who shall then act as President, or the manner in which one who is to act shall be selected, and such person shall act accordingly until a President or Vice President shall have qualified.
There will probably be a new election, regardless of what scenario goes down. I wish that wasn't the case, because we all know what happened, but I think that's the most likely scenario.
