He won't concede because he can't get through a concession speech without suffering a severe emotional breakdown. Think back to some of his debates with Hillary where he's was raging and sniffing. Multiply that by 1000. Now he's got to admit that he lost to basement-dwelling, mask-wearing, "cognitively challenged", "Sleepy Joe" who hasn't done anything in 47 years in his view. The last time he spoke, I would swear he had to be on some anti-anxiety medication which came off as the lobotomized version of Trump. They went too far with it. Maybe if they get the medication just right Trump can pull it off without crying like a baby, but I doubt it.
