About The Vote Ledger

Make it hard for a politician to rewrite their own record.

Political websites can be edited and a social account can be scrubbed. A roll call cannot. The Vote Ledger puts every recorded vote since 1789 in one place and measures, for each member, how often they sided with each party's majority — never looking at the label they wore.

Principles

01Sides, not labelsParty is never an input. A switch shows as one continuous line.
02Every number traces to a voteEach percentage names what it was divided by, and every vote behind it can be opened.
03Say what is missingBlank is never shown as zero, and nothing is filled in by hand.
04A score is not a ratingIt says which side a member voted with. It does not say whether that was right.

How it is built

Roll-call records come from VoteView at UCLA. A pipeline scores every member, checks the results against sources the data did not come from, and builds a static site.

Advertising

The Vote Ledger is supported by advertising. Every ad is labelled, sits in a fixed slot so nothing on the page jumps, and never appears inside a chart, a table or next to a score. What an ad can and cannot see of you is on the privacy page.
