In November when Twitter got excited for a day about Bernie I bet Biden to win the nomination at 4:1. In April, as COVID tanked Trump's approval, I got 2:1 on him to win the election and popular vote, the latter seemingly guaranteed.
In August PredictIt gave me 1:5 on Joe merely staying in the race. I bet him last week at 2:3 when models gave him 85-90%, then tripled down late night on Tuesday when he was a 2:1 underdog despite many smart people talking about outstanding Blue mail-in and big city ballots.
