What does LA Ballot Match do?

It helps fill out a Los Angeles County ballot: you take a short quiz, enter your address, and it returns a match for every contest on the November 3 ballot, from governor down to the water board.

What roles do the models play?

The author splits the work: Claude did the research behind each contest, and Jev does the scoring that maps your quiz answers to a candidate or position per contest.

Is LA Ballot Match open source?

Yes. The author says it is open source so you can check the logic or fork it; the build is hosted at la-ballot-match.vercel.app and shared by the author on X.

Who built LA Ballot Match?

Bret Morris, who posts as @4bret, built it as a civic tool for the November 3 election and shared the open-source link alongside the live site.

Does it decide my vote for me?

It produces a match for each contest from your answers, so it orders candidates by fit rather than casting a vote; the decision on each office stays with you.

Why use Jev for this instead of an LLM?

Ranking each contest from quiz answers is a bounded scoring problem, which Jev handles as a typed score, leaving the open-ended research and explanation to the language model.

Is the information authoritative?

It is a community-built helper, not an official source, so verify your final ballot against the county's own materials before relying on it.
