However, I firmly believe that if Obama loses, he will declare the election null and void and appoint himself grand exalted poobah, president for life or some such. As we have seen, he has used the executive order way beyond what it was intended, and neither Congress nor the courts have done anything to stop him. So who or what will stop Obama from making himself a dictator?
Secret Service agents. Capitol police. The military.
I don't expect your scenario to even be attempted.
