Good question.Trump has the hyper masculine Giuliani and millions of lock-stepping, well armed supporters at his side. By the way, who does the Secret Service report to? Are they under Homeland Security or possibly DOJ?
If ordered to continue protecting Trump in the Whitehouse post inauguration, will they obey?
The only chance otherwise is if his advisors convince him to run in 2024 and behaving like a rational adult now will help him.Trumps ego is hurt, the only actions he will take now are to hurt Biden and hurt the country to make ot pay for not reelecting him, watch and see.
Hope I am wrong but its not looking good.
