Biden was able to do a little Scranton magic in an extremely unfavorable COVID election against Trump but this is now a lost generation that was explicitly rejected when Obama picked up the phone before South Carolina got all the moderates to drop out, endorse Biden and get the entire DNC threw their support behind him while also Liz Warren stayed in so she could come in 3rd in her home state and split the left everywhere.
“For every blue-collar Democrat we lose in western Pennsylvania, we will pick up two moderate Republicans in the suburbs in Philadelphia, and you can repeat that in Ohio and Illinois and Wisconsin.” Chuck Schumer, 2016.
This is going to haunt the dems for a long time.
