What did you expect? Did you expect him to go mad and lose himself?
No, I think the OP expect him to show a soft side of been human which I'm sure his congratulation message to Biden have already express it cause he once had disputed with Barack Obama during his administration as the US President while Biden was Vice then and hes sure that the issue wont be hidden from Biden.
Not everyone is as arrogant as Trump LOL
By the way, I had a small bet with Biden and I got the winning yesterday. It was a nice return.
Speaking of Trump been arrogant, I believe his arrogant in nature was the reason why he dont wont the election.
Congrats for your winning though and for those have you guys they may also want to bet in the 2024 election follow Professor Allan Lichtman his predictions seems to be intact for over 10years now.
