Hilary Clinton was given a 98% chance on Election Day. I’m not confident of him losing.
I also don’t think Biden would be a good president. He’s still pretty awful on the key things in the spotlight right now, like race relations, and police militarisation and violence. Better than Trump, less despotic, but he does have authoritarian tendencies as well, and the Democratic Party wouldn’t throw up token #resistance against Biden.
Frankly the political class in the US (and to an extent here) fill me with little hope for the future. It’s only the people in the streets pushing back that give me anything.
