Fix the Senate I: Scrap the filibuster
The United States Senate is a catastrophe.
It is prima facie anti-democratic: 38 million voters in small states have 15 times the representation as California’s 40 million voters. Extra-constitutional Senate rules and practices, most notably the maximalist filibuster, have turned the body into a “kill switch“, one veto point to rule them all. They have enabled a minority faction to block and obstruct, to prevent any constructive governance at all except when it will redound to the political benefit of that faction. Institutions of government matter. “Democracy” is not some free-standing good thing. If it is to be good, and if it is to survive, it must be embodied in particular, functional institutions. In the contemporary United States, that is not the case.
The Senate is hard to fix. Disproportionate representation of citizens in the Senate (described as “equal Suffrage” of states) is specifically excluded from amendment by the Constitution. In this series, I’ll describe three reforms that I think would improve the Senate, ordered from least to most speculative. The first is easy to enact and very widely discussed. I’ll just add my voice to the chorus.
Right now, this week, we should improve the Senate by eliminating the filibuster. Ryan Cooper has an excellent piece on how this would work (with a pointer to Akhil Reed Amar, whom I love for his work on lottery voting).
I’ve come to oppose the filibuster reluctantly and with some sadness. In a better-arranged polity, modest supermajority requirements might play a useful role. A democracy at its healthiest governs by persuading a broad center, rather than lurching back and forth between irreconcilable agendas of hostile but nearly balanced factions. In defiance of the median-voter-theorem, tack-to-the-center claims made on its behalf, the United States’ two-party system, has reshaped us into two hostile factions, nearly balanced not in absolute numbers but in terms of how our system translates numbers into power. We are, as Lee Drutman puts it, caught in a “doom loop” that is entirely an artifact of a bad political system, not the existential struggle between distinct peoples too many of us are lazily permitting themselves to conceive. Simple majoritarianism is a cause of this catastrophe, as it tempts people to govern with 50% + 1 coalitions that entirely ignore the values and interest of the other 50%. This is an ugly kind of polity. However, the Senate’s effective supermajority requirement via the filibuster has not overcome the incentives of the two political parties, and the incumbents they run, to divide us. It has merely incapacitated us. The filibuster has become a minority veto, which, given the disproportionality of representation within the Senate, could in theory be exercised by Senators elected by fewer than 10% of voters. In practice, it’s not quite that bad, but still terrible. Under current circumstances, a blocking coalition of Republicans can be mustered from Senators representing only 25% of the population, elected by a share of voters even smaller than that. (Even in red states, Republican senators occasionally receive less than 100% of the vote.)
There is a case to be made for a supermajority legislative threshold. But an effective 75% threshold in terms of population represented (ignoring incomplete support among voters) is a prescription for paralysis. Worse, the threshold is asymmetric. While Democrats face that 75% threshold, Republican-backed initiatives pass with assent of representatives of only 54% of citizens. This is an institutional embodiment of “my way or the highway” for the Republican Party. Both parties can force inaction, only one can enable it, despite approximately balanced support within the population. [*]
A principled supermajority requirement might be established in the House, rather than the Senate, in combination with redistricting or other reforms that ensure representation in the House is proportionate to voter support. The current Senate filibuster is simply indefensible. The Democratic majority should scrap it, today.
[*] A bit of an irony that I’ve not seen discussed is that in 2020, Democrats gained control of the Senate, but actually lost the chamber’s overall popular vote to Republicans by a slim margin. (The numbers cited exclude the George special election results, but they’d not change the basic picture.) In 2018 and 2016, however, Democrats won more Senate votes than Republicans, by substantial margins, but did not win control the chamber. Obviously, the US Senate’s composition during any given Congress reflects the results of three elections, so even if we adopted a voting system that made representation in the chamber proportional by party to overall votes received, a given cycle’s winners would not necessarily gain control. However it’s a bit weird and wacky that Democrats gained seats and control during a cycle when they lost the popular vote, while in 2018 Democrats lost seats despite a blowout popular vote win. The quirks in our system can cut both ways.
