More importantly Republicans have shown time and again they are willing to consistently hold their positions without any expectation they'll have to compromise and berate other legislators and bully around to get what they want, I don’t want to see democrats give in to that again and again and again
EDIT: Couldn't Biden do an end run around the Republicans by strategically calling an emergency session after hours via Article II, Section 3 of the constitution? It has no requirements that the majority leader be there to start quorum, only that the session has been declared. Then attending democrats could just vote this thing through and call absence on the rest
