About the data

Votes come from Voteview (UCLA), refreshed weekly. Recent votes were cross-checked against the House Clerk. Positions are shown as Yea, Nay, Present or Not voting. Roll-call numbers match the official numbers where they exist. Cite as: Lewis, Poole, Rosenthal, Boche, Rudkin, Sonnet. Voteview: Congressional Roll-Call Votes Database, voteview.com.

Results are limited to 50 rows per call. If something looks wrong, tell us at Support.
