A sense of affiliation that a person has with a particular political party.

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

Answer: (B)

Party identification is a person’s enduring sense of belonging or loyalty to a political party, which shapes how they interpret politics and decide whom to vote for. It acts as a simple heuristic that combines beliefs, values, and trust in the party’s candidates, making voting decisions more predictable over time. This affiliation tends to be stable but can shift after major experiences or events. By contrast, interest groups are organizations that advocate for specific policies, an open primary is a voting method that lets voters choose a party’s primary regardless of affiliation, and litigation is a legal process. So the feeling of affiliation toward a party best fits the idea of party identification.
