A party cue is a signal from party leaders or other trusted partisan sources about how to interpret a current proposal, event, or candidate. Cues lower information costs. A voter who has not studied a complicated budget may use agreement among trusted party figures as evidence about what the proposal means. Cues tend to be clearer when party elites agree and the source is trusted. They weaken when prominent copartisans divide, the voter possesses strong prior knowledge, or direct experience contradicts the message.

Ownership and cues are related but not interchangeable. Ownership is a standing reputation-"this party handles environmental protection well." A cue is a present communication-"leaders of this party support this particular emissions bill." Party identification describes the voter's attachment to the party supplying the cue. A person can identify with a party yet reject its cue, and a party can send a cue on an issue it does not own.

These concepts explain influence without assuming manipulation or blind obedience. Voters use shortcuts because attention is limited, but they can compare sources, learn from events, and change their minds. Polarization may make elite cues more consistent while encouraging supporters to interpret facts through opposing partisan frames. Match the evidence to the mechanism: a reputation for competence signals issue ownership; an endorsement that changes interpretation signals a cue; a durable personal attachment signals party identification. A platform committee combining demands is performing interest aggregation rather than creating either informational effect.
