How to interpret this record
U.S. Election Data, Charts, API, and Downloads
A useful public record has an identity, a scope and a source. Research becomes more reliable when those elements travel with the number or statement being discussed.
Write down the claim first
Identify exactly what you want to know: who holds an office, whether someone appears on a ballot, what a committee reported spending, or how a member voted on a question. Each claim calls for a different source. A biography, a campaign website and a financial report can all be useful without answering the same question.
Keep identity, scope and date together
Record the entity identifier, jurisdiction, election or reporting period and source publication. These details prevent a correct fact from being attached to the wrong person, place or time. A name-only match can be misleading, especially when campaigns or institutions have changed names or when a person has sought several offices.
