Ohio's least partisan county (50,000+ voters): Butler (modeled; Ohio voters don't register by party)

43.84% of voters in Butler County have no modeled party lean, compared with 36.47% across Ohio. That's the highest share of any Ohio county with at least 50,000 voters. Ohio doesn't register voters by party, so these figures are modeled.

Primary Rules

How Ohio's Primary Works

Ohio uses different primary rules for state/congressional and presidential elections

State / Congressional

⚖

Open Primary

Any registered voter can vote in any party's primary, regardless of their own party affiliation or registration status.

How It Works

On election day, voters choose which party's ballot they want. They don't need to be registered with that party. In most open primary states, this choice is made privately at the polling place.

IVP's Position

Better than closed primaries, but still forces voters to pick a party's ballot rather than voting for the best candidate regardless of party.

Presidential

⚖

Semi-Open Primary

Voters don't have to publicly declare a party affiliation, but they must request a specific party's ballot at the polling place.

How It Works

Similar to open primaries, but the party whose ballot you request may be recorded. Some states allow parties to restrict their primaries to registered members, creating a hybrid system.

IVP's Position

Marginally better access for independents, but the party-based structure remains the core limitation.
