- Arizona: The primary is considered semi-closed. Unaffiliated voters may choose which party’s primary they will vote in, but voters registered with a party can only vote in that party’s primary.[4]
- Colorado: The primary is considered closed, but unaffiliated voters may choose to affiliate with a party on Election Day in order to vote.[8]
- Connecticut: Though parties may decide to hold a semi-closed primary election, the primary is considered closed as neither the Democratic Party nor the Republican Party allows any voter but those registered with their party to vote.[4]
- Idaho: Parties decide who may vote. The Democratic Party allows unaffiliated voters to vote in their primary. The Republican Party allows only voters registered with their party. Unaffiliated voters can choose to affiliate with a party on election day, but they will be bound to that party at the next election as well.[4]
- Illinois: Voters do not have to register with a party, but they do have to choose, publicly, which party’s ballot they will vote on at the primary election.[9]

- Nebraska: A blanket primary system is used for the nonpartisan legislature and some other statewide races.[15]
- New Hampshire: Unaffiliated voters may vote in the primary, but in order to so they have to choose a party before voting. This changes their status from unaffiliated to affiliated with that party, unless they fill out a card to return to undeclared status.[16]
- North Carolina: Parties decide who may vote, and they opened the primary election to unaffiliated voters. They may choose which ballot they want to vote on without affecting their unaffiliated status.[17]
- Ohio: Only affiliated voters can vote for candidates in the primary election; however, voters do not choose their affiliation until election day, when they request a party’s ballot.[18]
- Oklahoma: Parties decide who may vote, so an unaffiliated voter must be authorized by a party in order to vote in the primary.[19]
