Everybody is celebrating a, "blue wave" and a, "democratic victory" but the painful reality is, as long as the filibuster exists in the senate, the republicans can block a good bit of the progress and un-fucking the democrats might want to accomplish.
In order to really have a true "blue wave", there needs to be a "Supermajority" in Congress, enough votes to stop a filibuster and a Veto from the president.
The democrats have effectively not had a super majority in most peoples' lifetimes, and thus this is one reason why they get a bad rap as being "ineffective." It's really important to understand how things get done in government and when you have a party like the republicans who will -- on principal -- refuse to cooperate with the democrats even on common-sense legislation, they create a scenario where they can effectively demonize the dems for getting everybody's hopes up, and then letting everybody down.
This is why the republicans tend to make gains every other election -- because they know if they OBSTRUCT, the American publics' short attention span (exacerbated by corrupt media) won't realize who's really at fault and simply blame it on whatever party seems to be, "in power."
You rarely see this with the democrats. They aren't a monolithic group like the GOP. They are basically a "catch-all" of everybody else who isn't a white, Christian-nationalist who loves guns but hates abortion, immigrants, LGBTQ people. They will cross party lines to vote for legislation that helps people. The republicans could care less.
So you realistically can't expect the democrats to all vote in lock-step. They understand that politics is ultimately the art of compromise, and it's better to move one step ahead, rather than 10 steps backwards.
Case in point: During the Obama administration, the democrats briefly -- very briefly -- had a majority in Congress and managed to get the Affordable Care Act passed. However it was not without compromise.
Ironically, their main section of, "Obamacare" never got passed because they didn't have enough votes to stop a filibuster That part was called, "The Public Option." I was basically, "Medicare for all" but they couldn't get the ACA passed with it included so they compromised to at least get more protections, more subsidies, wider access to healthcare and put an end to, "pre-existing conditions."
Now people are demanding the Democrats, "fix healthcare now" but again, they're in the same situation they were decades ago. They need 6 more seats in the senate to really make a difference.
So the fight hasn't been won. The democrats still do not have enough of a majority to accomplish what the American people expect of them, and most Americans do not seem to understand this and will still hold them accountable for things they cannot do by themselves.
