Washington would take a horsewhip to Obama and escort him out of the White House. But in an exquisitely polite manner, of course.
The former president of the Constitutional Convention would also explain how under the NBC clause Obama never had the right to be there. All the actions of his administration were thus null and void, all his appointees no longer worked for the government and had no further claim on the public purse. Having slain the Obama dragon in one stroke President George would then start hewing away at the unconstitutional actions of the prior two centuries. Realizing from his experience fighting King George, that he couldn’t win them all as quickly.
