Replication data for: New Measures of Partisanship, Ideology, and Policy Mood in the American States

These measures improve on existing methods for estimating state-level preferences because the surveys provide larger state samples without pooling across years. After detailing our methods for constructing the measures, we assess their validity through comparisons with measures already in use by scholars of state politics.

We find that our measures correlate strongly with those created by Erikson, Wright, and McIver (1993) and Berry et al. (1998) and with measures from state-level polls. We conclude that our measures can be useful to research in state politics.
