In this article, I center substantial improvement in subnational democracy in the U.S. states as an object of inquiry and seek to explain it. I theorize that strong unions, high Democratic Party control of state government, an especially liberal Democratic Party, a large population of people of color, and a particularly liberal public mood may each contribute to substantial improvement in democratic quality. Using Coincidence Analysis (CNA), a configurational causal method, I assess the evidence for my hypotheses. The CNA identifies three alternative paths to substantial improvement in electoral democracy in the states. The results of my analysis highlight that substantial improvement in electoral democracy is the product of political struggle centrally involving unions and the Democratic Party.
