The short version.
Idaho nominates most candidates through a partisan primary: each party holds its own primary in May of even-numbered years, and the winners advance to the November general election. To get on the ballot you file a declaration of candidacy and pay a filing fee — or, in place of the fee, submit a petition in lieu of the filing fee (Idaho Code § 34-626). County and local candidates file with the Washington County Clerk; state, legislative, judicial, and federal candidates file with the Idaho Secretary of State.
This page covers how that works for Washington County. It is not legal advice — your county clerk and the Idaho Secretary of State's candidate-filing page are the sources of truth.

Public presidential-election returns for Washington County. A registration edge in a primary is often decided by a few hundred reliable voters — which is where a real field operation pays off.
How to get on the ballot in Idaho.
There are two routes onto the ballot, and both start with a declaration of candidacy filed during the official window.
Path 1 — Run in a party primary.
File a declaration of candidacy during the filing period and include either the filing fee or a petition in lieu of the fee. The fee amount and the number of petition signatures depend on the office. A note on Idaho's primary: the Republican primary is closed — only voters affiliated with the party may vote in it — while other parties may open their primary to unaffiliated voters. Winning your party's primary puts you on the November ballot.
Path 2 — Run as an independent or for a nonpartisan office.
Independent candidates file a declaration with a petition of qualified electors and go straight to the November general ballot. Nonpartisan races — judicial seats and many city, school, and special-district offices — run on their own calendars and filing rules.
How the filing calendar works.
Idaho's calendar repeats every cycle even though the exact dates shift year to year:
- The primary election is held in May of even-numbered years; the general election is the first Tuesday after the first Monday in November.
- The candidate filing window opens in late winter and closes in spring. The deadline for state, federal, legislative, and judicial candidates falls a couple of weeks before the deadline for county, local, district, and precinct-committeeman candidates.
- Write-in candidates file a separate declaration of intent closer to the election.
Because the exact filing dates and fees change each cycle, we don't print them here — check the current calendar on the official Idaho candidate-filing page. State and federal candidates now file online at run.voteidaho.gov; county and local candidates file with the clerk listed below.
Offices on the ballot.
Idaho voters elect federal offices (U.S. House and Senate); statewide constitutional offices (Governor, Lieutenant Governor, Secretary of State, and others); the Idaho Legislature (State Senate and House); judicial offices; county offices such as commissioner, sheriff, clerk, assessor, treasurer, coroner, and prosecuting attorney; precinct committeemen; and city, school, and special-district seats.

After you qualify: building a field operation.
The paperwork ends the day you file. What starts then is the actual campaign — knocking on doors, recruiting volunteers, and identifying the voters who'll show up for you in May and November.
That's what Motion51 is built for. The Washington County voter file is already loaded — no chasing a CSV or paying a vendor. You scope your district, recruit volunteers, cut turf, and start knocking. The app works offline for areas with bad cell coverage, and every door is logged with a timestamp.
If qualifying is settled and you're thinking about the field operation, our For Candidates page walks through the next steps.
