New Hampshire Voting Rules 2026: Primary, Registration, Early and Mail Voting

A ballot brings together several decisions that share an election date but may follow different rules. The office, jurisdiction and stage of the election tell you what each choice means.

Start with the office and the place

An election record describes a particular office or question in a particular jurisdiction. A statewide contest is different from a congressional district, a city council seat or a school district. An address can help connect those boundaries, but a ZIP code alone is not a guarantee of one exact ballot. Use the election authority’s own ballot lookup to confirm the final choices for a voter.

Separate a filing from a ballot appearance

A campaign-finance filing tells you that a financial record exists. It does not, by itself, establish that the person qualified for the November ballot. A primary participant, withdrawn candidate and certified general-election candidate can all leave public records. Read the election stage and the source label before treating a directory as a current candidate list. Registered write-in candidates are a separate category whose rules depend on the jurisdiction.
