I would not be surprised to find out that the Clinton wing of the socialist Democrat Party is behind this latest business about Obama's birth.
My point being is that if Obama should be forced out then Biden is in line to be president. If Biden should become president maybe he'd appoint Hillary as his VP to throw a bone to the Clinton-bots in the party.
"At what point will Zero be forced out?"
It's hard to say. I would guess he'd go when the Democrat Party media starts turning on him by constantly badgering Obama, his staff, and Dem officials about Obama's constitutional qualifications to be president and then the Congress grows a pair and starts impeachment proceedings against him or goes to the Supreme Court about it.
Obama has one ace in his sleeve for this: he was duly elected, and he can say that it’s not HIS fault he wasn’t verified — that it’s Pelosi’s fault, because she ultimately OK’ed his eligibility. This is a case that could be argued on Obama’s side, preventing him from any impeachment. He never swore he was eligible, did he?
He would not be able to run again unless he proves eligibility, though.
