He would resign, stating that Americans were not worthy of his leadership.

I don't see him ever admitting that he was losing. I can see him fighting with all of the powers of the Presidency, legally and illegally.
I can also see the Supreme court backing his illegal actions. Big money is going to back him to the hilt, and we know where the Senate stands.

The Democrats hold a marginal lead on 1/4 of the real power of the government. We are the underdog here.
