I keep reading posts online about "Democrats are not helping people". What are they supposed to do? March over to the senate and get the republicans in headlocks until they pass some of the house bills, and then go over to the White House and threaten Trump with physical violence until he signs them?

Specifically, they are blaming Biden. He's a professor at University of Pennsylvania, not an office holder. Sanders is at least a senator, though he's not even a member of the minority party!
