Even if Biden is boring, he's a good man to lead the US out of the quagmire it's in at the moment.
Trump is totally amoral, whereas Biden has experienced loss in a way that few can imagine. He's not perfect, but he knows how to play the congressional game and when he reaches out to people looking for change in the police who have lost a loved one you know he isn't lying.
The alternative was also Bernie, which I just cannot see ending well.
