They know Biden will lose they are hoping Joe will deliver the down ticket races I dont see how if Joe loses he delivers the down ticket can some please explain!!!
I believe they think with Biden they will lose less of the down ticket races than they would with Bernie. They just want to minimize the losses.
If that is the plan, they are hoping that older white Democrats who like Trump will still see the down-ticket candidates as acceptable choices since the party did nominate a "moderate' like Biden at the top. If the party picks Sanders, they would be facing total rejection by the white working class.
