Donald Trump will use whatever means necessary to retain his presidency including the use of armed force. It’s called a coup or coup d’état. Or is it I’m going to make you an offer you can’t refuse. 

He has at least three things he can do to retain the presidency.

1. Persuade electors to vote for him despite the actual popular vote. He might call them trying to convince them that there was fraud in the election. They might agree to take bribes.  Those bribes may not be money but promises of help in future elections or help for their states.  Maybe some threats like gangsters would use. Don Vito Corleone, in The Godfather: “I’m going to make him an offer he can’t refuse.” 

2. Implement a coup or coup d’état through violent means. There are already para-military groups and others who have said they will take up arms to ensure that Trump is inaugurated on January 20.

3. Support Texas GOP chairman Allen West who has proposed a secession of some states.

Is any of this likely?  It may be in Donald Trump’s world.
