It's not at all difficult - if one just puts forth the tiniest effort - to find plenty on the hardcore Left who are pretty pissed off that the ticket has two moderates. I can provide some examples upon request.
Trumpsters will convince themselves and each other that Biden and Harris are radical pinko commie Hitler Nazi Chinese Benghazi socialist Marxist Khmer Rouge Fascists who would roll in the tanks at the end of Inauguration Day, but the rest of the country isn't intellectually paralyzed and turned full drama queen goofy by partisan paranoia.
Get a grip.
