Replication Data for: Are Donation-Based Measures of Ideology Valid Predictors of Individual-Level Policy Preferences?

This repository contains all the code and data needed to replicate the tables and figures in "Are Donation-Based Measures of Ideology Valid Predictors of Individual-Level Policy Preferences?" and the supplementary appendix. Abstract: This paper validates donation-based measures of ideology against a rich battery of policy items from the Congressional Campaign Election Study (CCES). Donation-based measures are powerful predictors of policy preferences for a wide range of issues and successfully discriminate between donors from the same party. The overall predictive accuracy and relative improvement over party are comparable to what is achieved by scaling roll call votes in legislatures. The results add to an existing body of evidence on the internal validity and reliability of donation-based measures. They also resolve a standing debate in the literature over whether political donations are a valid indicator of donors' policy preferences.
