An election to choose candidates that is open to independents, and in which voters may choose candidates from any one party.

• A. Party Identification
• B. Interest Groups
• C. Open Primary
• D. Midterm Elections

Answer: (C)

Primaries determine which candidates advance to the general election, and this question focuses on how an open primary operates. An open primary is a primary election in which voters who are not registered with a party (independents) can vote in any party’s primary ballot. You may choose candidates from one party on that ballot, but you typically vote in only one party’s primary during that election. This differs from a closed primary, where only registered members of a party can participate.

This concept fits the description because it highlights the openness to independents and the ability to select candidates from any one party on a given ballot. The other ideas don’t describe this voting method: party identification is about a voter’s long-term attachment to a party, not the mechanics of primaries; interest groups are organizations that attempt to influence politics, not how ballots are opened to independents; and midterm elections refer to the timing of elections, not who may participate in party primaries.
