Replication Materials for Party Issue-Profile Change and Voter Retention: Comparative Evidence from CSES and Manifesto Data

This repository provides analysis code, aggregate statistical results, sensitivity analyses, figures, and verification records accompanying the manuscript "Party Issue-Profile Change and Voter Retention: Comparative Evidence from CSES and Manifesto Data." Original CSES and Manifesto Project data and restricted derived analytical datasets are not redistributed. This is a code-and-results archive rather than a self-contained replication package. Full reproduction requires obtaining the source data from their official providers. The archive documents the corrected confounder estimates and the limitations of independent reproducibility.
