The sad part in all of this, is how Trump supporters continue to be disillusioned and swayed by lies and deception.
Biden  isn’t just 'winning in the courts.' He handily won the popular vote and  won the electoral college votes by the same margin Trump did in 2016.   Remember that, the victory Trump called the 'greatest ever in history?'
This  idea of election fraud, that Biden won 'by cheating' has been  summarily rejected by courts all around the country for over a month now,  by liberal and conservative judges alike. Each time the Trump/GOP  lawyers had a chance to make their case based on evidence, it was  rejected out of hand. This is separate from, and in addition to, the 9-0  ruling by the Supreme Court.
Trump has also lost in the court of  public opinion, being the first President in history to never have  reached a 50% approval rating at any point during his time in office.
Trump Approval Index History ... 08-Dec-20, -2, 38%, 40%, 49%, 50% ... 24-Nov-20, -6, 37%, 43%, 48%, 50% ... 29-May-20, -10, 33%, 43%, 46%, 53%
I  get it, facts and the truth hurt. After four years of Trump and his  base kicking sand in everyone's faces, now the tables are turned. With  Trump heading out of office after a single term, MAGA's are shocked and  surprised not everyone is bummed out about it.  Nobody is gloating, it  just seems that way to you guys. 
If you want to blame someone  for the way people are reacting, blame Trump & the GOP, who won't  concede defeat, are whining, kicking, and screaming to the very end.  When your President and party acts like a petulant child, don't be  surprised when people react to that in kind.
I think the most  significant and cathartic event in this entire election was what  happened with CISA Director Christopher Krebs. You know, the guy Trump  himself appointed to head the election cybersecurity effort. When Krebs  came out and declared what a great job the department has done in  warding off election fraud and manipulation, something all Americans  should be happy about and proud of, Trump fired him. Yes, Trump fired  him, because he wouldn't go along with the lies and deceptions he and  Giuliani were cooking up, to turn this election around somehow, someway.  That's all you need to know about who the bad actors are. 
Maybe  in a few years more of you will come to realize the truth about Trump,  and understand the danger he represented to the country, to the Republic  and to the democratic principles the country was founded on. That will  be a welcome turn of events, if it ever happens.
