The President-eject

For political correctness's sake, President Obama, before he took his oath of office, was referred to as President-elect. Although it is obvious that there's no stopping Obama from taking the helm of US leadership, as Bush the Younger can not veto the inauguration day, and thus the former deserved to be called President, Obama is still addressed as President-elect until he is properly sworn into office.

But what do you call a person who has never been a President since 2004 but who acts like one, and whose mandate is severely questioned?

And yes, I am talking about GMA's staying in power. President-eject is perhaps an apt title.
