Also, I think this is all worth quoting,

The overarching argument is that public opinion doesn’t matter anymore because we’re no longer in the “normal” political space we’re used to.

This is categorically false, a basic misunderstanding of what politics even is.

… Politics doesn’t stop just because the President says it does or even when he’s in the midst of an attempted authoritarian takeover. Politics continues. Public opinion, if anything, becomes even more important. …

…

Public opinion matters a lot because public opinion is the ultimate decider, especially when it becomes lopsided against the government. It encourages more people to express their opposition and it makes the would-be autocrat’s supporters doubt he is strong enough to protect them from electoral backlash or even to remain in power.

…

… The opposers are the majority, in some polls approaching 60% of the population. When people realize this, opposers become more likely to speak out, to take stands, to have confidence that they may in fact be on the winning side.
