Sometimes I think I can be unreasonably impatient with idealists. There’s a role for explaining how things ought to be even if it’s completely unrealistic. A climate scientist might argue that we should stop putting carbon in the air starting tomorrow, and they probably can make a strong case to back up their position. They just shouldn’t expect politicians to take much time today trying to accomplish this, since it’s an impossible ask.

That’s kind of how I feel about the more than 200 political scientists who “have put forward a sweeping proposal to change the way the United States has conducted its federal elections for nearly 250 years.” Their idea is that we should do away with winner-take-all elections and adopt proportional representation. They make a great case for why this would be beneficial to the country, but it feels like wasted energy.

The obstacles should be obvious, beginning with the basic problem that you’re asking legislatures, which are by definition made up of people who have won under the current rules, to change things up so radically that their own positions and degree of power could be imperiled or diminished. That makes them unlikely to change state and/or federal laws, or to amend the U.S. Constitution.

Pragmatism isn’t necessarily antagonistic to idealism, but it deals in the realm of the possible. I’m reminded of this subset of health advocates who would rather not have people insured under the Obamacare reforms because the best solution would be a single-payer system. A lot of people suffered and died while nothing was getting done. Pragmatists stepped in and found a way forward.

Still, there was value in people advocating for single-payer and explaining the reasons. They helped the pragmatists make their case that something must be done.

It’s just hard to listen to people make unrealistic demands and harshly criticize people who won’t pursue their hardline dreams.

We can make progress on how our elections are financed and conducted, taking into account where we are as a country and how difficult it is to create fundamental change. I’d much rather see a plan for that than this open letter from political scientists.
