I'm watching PBS too, for the same reason;  they've got some good people.

I think young people will come out.  With Sanders and Warren urging them to back Biden, with Trump as the alternative should encourage them even more.

One thing this time, there aren't two other Democrats running this time to take votes away from Biden, as they did from Clinton last time.

The pandemic, though has done somewhat the same thing.  With 50% of deaths being older black and brown--Democrat voters most likely, 85000 votes can be a lot in swing states. Then, too, how many of the other deaths represent Democrat voters?
