Replication Data for: How Partisan Are U.S. Local Elections? Evidence from 2020 Cast Vote Records

Replication Data for: How Partisan are U.S. Local Elections? Evidence from 2020 Cast Vote Records Abstract: Analyzing nominally partisan contests, previous literature has argued that state and local politics have nationalized. Here we use individual ballots from the 2020 general elections covering over 50 million voters to study the relationship between individual national partisanship and voting in over 5,700 contested down-ballot contests, including nonpartisan races and ballot measures. Voting in partisan contests can be explained by voter's national partisanship, consistent with existing literature. However, we find that voting for local nonpartisan offices and ballot measures is much less partisan. National partisanship explains more than 80 percent of the within-contest variation in voting for partisan state and local offices but less than 10 percent for local nonpartisan contests and local ballot measures. Further investigating local ballot measures, we find noticeable variation in partisanship across topics. Finally, we find some evidence for structure in the pattern of votes on local spending measures.
