There remains one more way to stop a Trump Presidency under normal procedure. That is for Congress to reject Electoral votes on January 6 in sufficient numbers to send the election to the House. The House would then have to elect a President.
Normally an optimistic sort, I must admit that unless people become aroused enough to demand such a procedure there leaves little other option for stopping the mogul from Manhattan, except...
There are always miracles, of course. And believers should definitely be praying for a miracle now. Miracles do happen.

Third, and crucially important -- yet often overlooked -- the media must help get the word out about the voter suppression tactics used by Republican operatives in this and other elections.
Fourth would be a mass political movement of the Arab Spring type.
