The DSA and Working Families Party are increasingly active in Democratic primaries and, for cities with nonpartisan ballots, first-round elections. City & State consequently reports that New York City Mayor Zohran Mamdani’s new charter-review commission has been swamped with calls for “open primaries.” Out on the West Coast, however, “open primaries” are producing the same basic results.

I want to suggest that cities like New York and L.A. instead consider increasing the sizes of their councils. Doing so might take some pressure off of Democratic primaries — or what passes for primaries in cities with nonpartisan elections.
