Replication Data for: The Changing Nature of Congressional Party Support in a Hyper-Partisan Era

This study explores whether members of the U.S. House have adopted a more stable, enduring support for party in recent decades, and whether there is less avoidance of divisive partisan votes in the lead-up to elections. We further examine the correlates of these behavioral changes, including the role of cohort replacement, electoral vulnerability, party size, party status, and calendar changes in the consideration of appropriations votes.
