Typical liberal, it's not so much about economic ideology as the rule of the constitution and law. Perhaps many don't realise that when they signed on for liberty, it meant for all, not just themselves. Liberalism is a process that is also bottom up driven and top down administered as the government responses to the will of the people to overcome other pernicious social forces like bigotry and greed. It is historical and inevitable, it is time and the strength of people to do it, there is inertia and interests in the status quo.
Take the situation of black Americans for instance, their movement for human rights gained traction and provided the spark that drove people into the streets in the midst of a pandemic, masks and all. Many were white and almost all felt their lives were at risk for showing up, and their movement has over a super majority of support, but lot of things do in America, republicans block, or distort change into meaninglessness through "compromise". Now that the parties are polarized, black people and other minorities hold as much power in the democratic party as the hardcare base of the GOP and if they gain power they will use it.
The top down implementation goes a lot better when ya got the implementers by the balls and almost total power. African Americans will have a seat near the head of the table of power, Obama was president first and an advocate for liberal causes second, it is his job, the POTUS does not have a second job, he had to deal with these assholes, look how much trouble there is to get a dime for the people out of the assholes. This time it will be real power with a mandate for change and a supermajority supporting it, that also includes pot legalization, Joe will gripe, but he will sign.
I expect at least 20 more house seats going democratic, maybe more, I also figure they will win the senate by a comfortable margin, Joe will be POTUS, provided he is still breathing. Dunno when Nancy will retire, but I figure she has a replacement talent spotted, I think she will drive through everything that was sitting on Mitch's desk before she goes. The democrats might not have 66 seats, but the the remaining republicans face 2022 and a world of hurt and shame from the many investigations, hearings and trials. The democrats will find the votes or rain down fire upon the weakest among them, the republican party will be a shattered wreck on fire when Trump is done wiping his ass with them.
