Today’s Supreme Court decision upholding the travel ban has renewed discussion of Mitch McConnell’s decision to prevent any Obama nominee to the Court from receiving consideration, and whether Democrats should run on packing the Court to redress this. If they did, they’d surely be greeted with deploring howls from centrist opinion makers in a way that Mitch McConnell was not. Michelle Goldberg points to a similar imbalance in the “civility” debate in a really great NYT piece today.

Naturally, all this has led to lots of pained disapproval from self-appointed guardians of civility. A Washington Post editorial urged the protesters to think about the precedent they are setting. “How hard is it to imagine, for example, people who strongly believe that abortion is murder deciding that judges or other officials who protect abortion rights should not be able to live peaceably with their families?” it asked.

Of course, this is not hard to imagine at all, since abortion opponents have assassinated abortion providers in their homes and churches, firebombed their clinics and protested at their children’s schools. The Roman Catholic Church has shamed politicians who support abortion rights by denying them communion. The failure to acknowledge this history is a sign of the reflexive false balance that makes it hard for the mainstream media to grapple with the asymmetric extremism of the Republican Party.

One of the big disputes among liberals and the left today is over norms. Some people who hate Trump, hate him because he is trampling over the norms that have previously restrained presidents and politics, and want a return to the status quo ante. Others hate Trump because they see him as the manifestation of a problem that has been there for a very long time – that the norms governing US politics have been systematically imbalanced in ways that favor the right, and that we’d be better off without them. This dispute has plenty of political dimensions – one of them is strategic. You can think of norms, like any informal rule or institution, from a game theoretic perspective, and see them as an equilibrium that represents the relative bargaining power of the two main parties in American politics. In this kind of analysis, as per Jack Knight and others, relative bargaining power depends on the breakdown values – the payoffs that people receive in the event that no agreement is reached. The less that I care over whether an agreement is reached or a norm is maintained, the more bargaining power I will have to shape that agreement or norm, so that it favors my interests rather than the other party’s.

Much of the implicit argument of ‘normcore’ people on the liberal side of politics has been that liberals and the left need these norms more than the right, because without them, we’d be even worse off than we are. In other words, liberals and the left are in a strategically weak position. They want to reach an agreement far more than conservatives do. Accordingly, conservatives are going to be able to bargain harder, because they are more indifferent to breakdown than liberals or left-leaning people are. From the normcore perspective, even if it is going to be a pretty cruddy deal, it is better than no deal at all.

But there’s another way to think about it. The more unbearable that status quo politics are, the less value there is to liberals and the left in reaching an accommodation. Under this logic, things are pretty shit already. They might be even more shit if we refuse to play ball, but who knows? Things couldn’t be much worse than they are – so why not try something different? The more that norms become a threadbare justification for a situation that is effectively that preferred by the side that is prepared to play hardball politics, the more likely that the other side is going to want to start playing hardball politics too. Their breakdown values are going to be higher when everyday politics is visibly breaking down.

I’ve seen (although I can’t find it right now) polling data suggesting that liberals, who have historically been much more interested in reaching agreement with the other side than conservatives, have now converged upon conservative preferences. The various self-organizing groupings around the country don’t seem to me, from what time I’ve spent with them, to be particularly ideological (for better or for worse). What they do seem to be is completely uninterested in compromise with the Republican party in its current configuration. Leaders like Pelosi and Schumer seem to be more attuned to the people writing hand-wringing editorials about civility than to the people whom they’re supposed to be representing. That’s probably not going to work out too great for them.
