What if Bernie Sanders had become Biden's running mate?

[BlueSwan]

Trump is a lifelong con artist who bragged about sexual assault on tape and yet still won and election nerd stiffs are like "Sanders would of cost Biden the election cuz he far left."

But this is America, even some in my family (Manhattan Dems) said they'd vote GOP over Bernie because he's a "communist"

Yup. Young people have no idea how the older generations view socialists/communists. A self-described socialist cannot win a US presidential election until demographics have changed considerably from now.
