The easiest—and best—answer to the problem is to beat him in the election. It will take less time and will not disrupt the civil peace.
This needs to be done anyways. All those B@stards on our side that kept hammering and mocking us on this issue need to get their comeuppance! They need to be demonstrated to be the fools who let this happen, and what's more sided with the ENEMY against their allies.
Erick Erickson, Ann Coulter, Allahpundit, Ed Morrissey, Ace of Spades, etc. all of these people need to be beaten over the head with their bad judgement on this issue. Obama needs to be proven ineligible also to undo his horrible judiciary appointments, and the legislation he signed. It needs to be done anyway. There needs to be an Asterisk * in the History books which says "This man was NOT a legitimate President."
