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.

本研究旨在探究近数十年来，美国众议院（U.S. House）议员是否对政党形成了更为稳定且持久的支持倾向，同时考察议员在选举前夕是否更少回避引发分歧的党派投票。本研究进一步分析了此类行为转变的相关影响因素，涵盖同辈群体更替、选举脆弱性、党派规模、党派地位，以及议员在审议拨款投票时的日程时序变动所发挥的作用。
