Graft and shenanigans.
Senator Joe Biden would become the President-Elect if Obama were to become unable to server as President (eg. death) beginning December 15, 2008. Should President-Elect Obama be unable to server as President prior to December 15, 2008, the day the Electoral College votes, several scenarios might happen. Some states are required by law to vote for their states voted candidate (ie. the President-Elect that can't server). Other states can't select whomever they choose. To answer your question, if it is after the Electoral College vote (12/15/2008), Senator Biden, if it is prior the Electoral College, it is unknown (Biden, Clinton, McCain, Palin, or someone else). This has never happened in US history.
