I know, the question in itself is pretty out there. But is this supposition a lot more believable today than it would have been 4-5 years ago?
BHO has acted in ways that has obviously exceeded his authority, the latest being as to Immigration. He knows he didn't have the Authority to usurp the current Immigration Laws, Laws that were passed by Congress. But he did it anyway. So in view of his actions to date, is it really that inconceivable to think that he might try and "extend" his stay in the WH?
If we had a catastrophic event, like a 9-11, late in his Term, I could see him make an argument that "at this critical time, it is in the best interest of the American people that we not lose the continuity of our fight, and that in leaving the fight now, would not be in the best interest of the American people, nor the incoming Administration."
The thought of this is not so extreme today. Not with this extremist President.
