Members' Votes

This data contains basic information about how each member in the selected chamber(s) and congress(es) voted on each vote.

Quick Link (all congresses, all chambers, CSV format): https://voteview.com/static/data/out/votes/HSall_votes.csv

Fields:

• congress: Integer 1+. The number of the congress that this member's row refers to. e.g. 115 for the 115th Congress (2017-2019)
• chamber: House, Senate, or President. The chamber in which the member served.
• rollnumber: Integer 1+. Starts from 1 in the first rollcall of each congress. Excludes quorum calls and vacated votes.
• icpsr: Integer 1-99999. This is an ID code which identifies the member in question. In general, each member receives a single ICPSR identifier applicable to their entire career. A small number of members have received more than one: this can occur for members who have switched parties; as well as members who subsequently become president. Creating a new identifier allows a new NOMINATE estimate to be produced for separate appearances of a member in different roles.
• cast_code: Integer 0-9. Indicator of how the member voted.
• prob: Estimated probability, based on NOMINATE, of the member making the vote as recorded.
