To what end? If this were a clubhouse, it might make sense. When we are talking about the upper house of our federal legislature where decisions that affect our rights and liberties are made, the stakes are slightly higher wouldn't you say?
I argue that easy institutional obstructionism in which little can be accomplished without a high degree of consensus and horse-trading is safer to live under nine times out of ten than unchecked untrammeled lawmaking power.
By all indicators we are pretty evenly split, by the last polling done in 2019 with Americans identifying
37% Conservative, 24% Liberal and 35% Moderate with both the left and the right claiming the Moderate swathe in the middle agrees with
them and thus putting their views in the majority. But taken in the aggregate, America has become more pro-gay rights, more pro-gun rights and more pro-life (on a personal if not legal level). I think a Democratic Party which is seen to engage in such a naked, cynical power grab (whatever their stated intentions at correcting Republican cheating) will be seen to be attempting the establishment of monopoly party control the likes of which we see in Venezuela and Turkey, and they will face a backlash that will cost them far more dearly and far more quickly than they anticipated.
After all remember what happened after the Affordable Care Act was pushed through a decade previous and the backlash the Democrats faced over that. And while a major change, the ACA was positively anodyne in comparison to admitting new states into the Union for no other reason than to gain safe Democratic seats and packing the Court with politically left-leaning judges and then propose changes to put the voting threshold at 60 in the Senate. That is a pure power grab. But not on behalf of a branch of government or even of a constituency. It only benefits the party in control and nothing more.
