Should the Worst Happen

I have some ideas on how we might refer to Joseph Biden:

• The Usurper-in-Chief (UC, for short)
• The Pretender of the Office (PoO - which is how we expect his administration to smell)
• Inserted, Not Elected (INE)
• 'President' by Massive Fraud and Chicanery (MFC - COULD also stand for M-F in Charge)
• and, of course, the classic - Not MY President

Add your own ideas to the comments.
