Political parties seem to have a problem today. Voters dislike being part of a political party and have choosen to register or refer to themselves as non-partisan in greater numbers today than in the past. Political parties have also lost control of their candidate nominations, and when a party makes a big push toward their preferred candidate, cries of corruption and system rigging erupt from the public.
However, at the same time, voters more consistently vote for a single party today than they did in the past. When we look at voters who register non-partisan and ask if they lean toward a particular party, we see that they overwhelmingly vote for members of that party in each election. Non-partisan voters who lean toward a party often end up voting along party lines at the same or higher rates as voters who are registered with a party. So while our parties seem to be loosing steam, partisanship seems to be growing.
Jonathan Rauch looks at this phenomenon from another perspective in his book Political Realism. He specifically looks at votes within congress and how congressional members seem to align within parties. Rauch writes,
“It’s often said that parties are stronger than ever because votes on Capitol Hill are so consistently partisan. But that can be (and usually is) because the majority party is allowing votes only when its factions agree, whereas machines facilitate decision-making when fellow partisans don’t agree. Ideological solidarity is a brittle glue, and reliance on it for intra-party cohesion is a sign of a weak party machine, not a strong one.”
What Rauch argues is that our parties need to find ways to create cohesion beyond ideology. Rather than relying on individual voter or policy maker issue stances to align, parties need to be able to bring different groups together within the political process. Parties which are only able to attract loosely committed voters fail to create a community of thoughtful and considerate political participants. The perspectives, views, and alternatives available to the party shrink, and in the public we see a fixation on a single issue from a single point of view, while in legislative bodies we see a limited number of votes on a limited number of partisan issues. This does not strengthen democracy, and easily breaks down, leading to the cynicism, criticism, and frustration that we see surrounding the American political system today.
I also think there is another phenomenon surrounding the abandonment of political parties and the staunch partisan voting pattern in the United States. Political identity is a powerful signal, indicating which group you are a part of and often influenced by both overt and hidden factors. In The Elephant and the Brain, Kevin Simler and Robin Hanson look at our hidden agendas and our group signaling in politics. We often don’t want to admin when we align with a party out of self interest or out of group identification. We hide behind a veil claiming that it is specific issues that drive our political alignment, but studies frequently show that almost no one has a real grasp of any given issue or any given legislator’s stance on an issue. What we are really displaying today, at least in part, is an institutional distrust driving us away from the parties that we complain about, but an identity stronghold in the claimed political philosophy that we back. Simler and Hanson may better explain why we see this pattern and if Rauch is right, then we must hope that machines can be built to activate local public action before dangerous demagogues use this identity and signaling undercurrent to divide rather than unite local communities.
