PartyLine was built to make congressional voting records easier to understand and compare.
PartyLine gives voters a clear, accessible view of what their elected officials actually do. We turn voting records and political data into understandable information so people can compare their own views with the actions of those who represent them and make informed decisions for themselves.
A democracy where every voter can see beyond party labels, campaign promises, and political rhetoric to understand how their representatives actually govern, giving people the information they need to make up their own minds.
Most political tools tell you what to think. PartyLine just shows you what happened. We don’t endorse candidates or take positions on issues. We show you who voted for what, and you decide what that means to you.
Every roll call vote in the House and Senate is public record. But for most Americans, that information is buried in technical language, long bill texts, and scattered government databases.
Modern political discussion focuses on headlines, speeches, and social media. Voting records are different. They are measurable, documented, and permanent.
PartyLine organizes that data into a clear, issue-based format so you can quickly see how elected officials actually vote, without commentary or partisan framing. We cover 13 key issues and score sitting members of Congress on their real roll call votes, once those votes cover at least three issues. Challengers who have never held office have no voting record. Where we find real evidence of what one believes — a campaign site, a Ballotpedia profile, a position they went on the record with — we use it and link it. For most challengers we find none, and what is left is an estimate drawn from party affiliation, which tells you about the party rather than the person. So a challenger has to have real positions on at least three issues before we will show a match score at all: about three in ten of the candidates you can reach today say “No score yet” instead of giving you a number.
Jacob Chapa is the founder of PartyLine. He spent 14 years in the U.S. Marine Corps, including serving as a Marine Raider with Marine Forces Special Operations Command (MARSOC), before earning his MBA from the Wharton School. He now works in management consulting.
Jacob has been a registered Republican and Democrat and has voted for candidates from both parties. That experience shaped his belief that most Americans are more complicated than the political labels assigned to them.
PartyLine grew out of a simple frustration: it was remarkably difficult to answer a basic question about elected officials — what do they actually do once they’re in office?
Jacob built PartyLine to make that answer accessible. By translating thousands of congressional votes into clear, issue-level records, PartyLine lets voters compare what politicians say with what they actually do, without telling users what to think or who to vote for.
His goal is simple: give voters better information and let them make up their own minds.
