We need political parties

The winner-take-all system

Unlike in other advanced democracies (most of which use various methods of proportional voting), the American legislative elections are held through a series of separate elections, each held in single-member districts, in which the candidate with the most votes wins. Because there is only one possible winner, any vote for a third party is essentially a “wasted vote.” This is the reason there are no third parties in the United States.

The deficiencies of a two-party system become glaring when the parties become as diametrically opposed as they are now. “A two-party democracy cannot provide stable and effective government unless there is a large measure of ideological consensus among its citizens,” writes the economist Anthony Downs in his widely cited classic An Economic Theory of Democracy.

The problem, as Downs explained, is that the country will swing from extreme to extreme, with each side antagonizing the other until the middle drops out entirely. In contrast to the ‘50s, the electoral system is now a faucet where the slightest change produce scalding and near-freezing water.
“When the distribution has become so split that one extreme is imposing by force policies abhorred by the other extreme,” Downs wrote, “open warfare breaks out, and a clique of underdogs seizes power." Just as George Washington feared.

To expand the party system to create space for possible centrist or other alternative parties would require a change in electoral rules create space for proportional voting. Earlier this year, Rep. Don Beyer (D-VA) introduced the Fair Representation Act, which would create larger House districts, and have the voters choose several representatives in each one. FairVote has a helpful explainer on how this would work. I wrote earlier this year about why this plan makes a ton of sense.
The system would give conservatives in New York City, for instance, a say in who gets chosen for the House: They would be likely to win a seat or two. Likewise, liberals in red Alabama districts might be able to elect a candidate. Ranked choice voting would mean citizens could vote their hearts — yet still express a preference for the “lesser evil” of the two major-party candidates.

The power of the presidency

The high-stakes winner-take-all dynamic is made worse by concentrating so much power in a single unilateral actor -- the president — who is asked to do something impossible: be the single tribune of very divided nation. (A difference of 80,000 votes in three key states, and the country swings wildly in a different direction: That is not a foundation for democratic stability.)

Some have observed that Trump is acting as if he only represents those who voted for him, rather than the whole country. Of course he is. When the country is divided, especially over fundamental questions of national identity, it’s impossible to govern from a nonexistent middle ground. Trump stays in power based on the support of a minority that also happens to be the majority of the majority.
This is precisely the danger of winner-take-all systems. All Trump needs is 60 percent support among Republicans (a narrow majority of the narrow majority); his poll numbers can stay in the low 30s and he can in theory retain power. This is how he is governing, because this is how the system is set up for him to govern under a divided public. He’s not going to win over any Democrats, and he has no incentive to try. This is why the power of the presidency is so dangerous. 

The Constitution deserves some blame for this situation, but a considerable amount of the expansion of executive power over the last several decades has happened because Congress has ceded authority and oversight. 

Changing this dynamic requires Congress reassert its authority — but Congress, of course, is also shaped by the dynamics of two polarized parties. 

Absent the structural revolution of a shift to multimember districts, a more modest change would be for both parties in Congress to decentralize internally. Under current organizational structures, party leaders dictate and control policy in ways that punish any rogue members who want to try something that wouldn’t help the party win the next election — like working across the aisle. 

That would require courageous votes from those entrepreneurial congressmen who would like to do much more freelance coalition building. But if they are willing to defy their leaders and whips, it would reveal that parties have far more internal ideological diversity than partisan voting patterns show.

For members to act independently, however, Congress would have to invest in more internal staff with policy expertise, and members have resisted such investments for a long time. 

A shift toward localism, or federalism, could help, too. If partisans on both sides felt more secure that they could live their values at home regardless of who was in power in Washington, this could lighten some of the zero-sum nastiness and dysfunction of national politics. For those on the left who have long seen federalism as code for mistreatment of minorities, the resistance of blue cities to Trump’s more draconian anti-immigration policies should offer some reassurance.

The outsized importance of private money in politics

Finally, there is the outsized role of private money in politics. Again, because one-party majority dominance is always narrowly in reach, both parties have been in a decades-long fundraising arms race that has consumed their ability to govern. 

In the campaign finance chase, both parties have gained profitably from catering to extremely wealthy individuals. In theory, the disconnect between voters’ wishes and donors’ priorities should create a problem for both parties, given that the parties economic policies are at odds with what most of their voters would prefer. But herein lies the great advantage of the two-party system — for party leaders. By dialing up the cultural conflict, they can distract voters from the disconnect between elite preferences and the public good. To the extent campaign finance reform can get politicians to refocus their attention on the economic needs of voters, not donors, that will help greatly in controlling polarization.

To return to the nightmare scenario I began with: Would Trump really refuse to concede, if he lost a close race in 2020? If so, would Republicans really stand by him? And if so, then what? Would the Courts step in? Would the military? Would Trump be forcibly removed from office? If so, what would he and his supporters do in response? Would a forcibly installed President Kamala Harris have to crack down on civil liberties in order to hold the peace? Would some deep red states then secede? 
These hypotheticals are meant mainly to clarify the stakes of our predicament. But given current trends, such a scenario is frighteningly in the realm of the plausible. The raw division and conflict and mutual demonization are there, and are getting worse and worse. The events in Charlottesville are just the latest manifestation. Where will things be by 2020? What happens if there’s a major recession, and even more anger?

I honestly don’t know whether we’ll get escape this mess without a constitutional crisis.
We need partisan conflict to organize politics. Without political parties, there is no meaningful democracy. But we are deep into a self-reinforcing cycle of doom-loop partisanship. We need to think hard about how to escape this trap, before it is too late.
