The short version.
Preble County, Ohio has 24,007 active registered voters across 65 precincts, as of June 2026. Here's what it takes to get on the ballot here.
Ohio has no party registration — you count as a member of a party if you voted in that party's primary within the last two years. To run in a party primary you file three things together: a declaration of candidacy, a nominating petition, and a filing fee. Independents file a nominating petition instead.
This page covers how that works for Preble County. It is not legal advice — for the official rules, your county Board of Elections and the Ohio Secretary of State are the sources of truth.

How to get on the ballot in Ohio.
Ohio doesn't have party registration. You're treated as a member of a party if you voted in that party's primary within the last two years (or haven't voted in another party's primary). There are two paths.
Path 1 — Run in a party primary.
File three things together by 4 p.m. on the 90th day before the primary: a declaration of candidacy, a nominating petition, and the filing fee. The petition must be signed by qualified electors who are members of your party (Ohio Rev. Code §3513.05):
- Statewide offices (Governor, U.S. Senate, Attorney General, etc.): 1,000 signatures.
- District & county offices (U.S. House, Ohio Senate, Ohio House, county offices): 50 signatures.
- Minor-party candidates need half those numbers.
Filing fees (§3513.10): statewide $150 · U.S. House / General Assembly $85 · county office $80 · judicial $80 · city $45 · village / township / school board $30.
Path 2 — Run as an independent.
Skip the primary and file an independent nominating petition (more signatures; Ohio Rev. Code §3513.257), due the day before the primary. Your name then appears only on the November general ballot.
You file with your county Board of Elections for county, local, and legislative offices, or with the Ohio Secretary of State for statewide and multi-county district offices.
What the signatures mean in Preble County.
The 50-signature minimum for a county or district office is a small fraction of Preble County's 24,007 active registered voters — for most candidates the real work is the paperwork and the fee, not the signatures. Aim to collect a cushion above the minimum, since the board verifies each one and a petition is rejected if it has too few valid signatures.
Exact signature counts and fees for your specific office are set by statute and confirmed by Preble County Board of Elections — check with them (or the Ohio Secretary of State's candidate guide) before you file.

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 Preble 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 neighborhoods 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.
