Political party identification refers to the psychological attachment or affiliation individuals have with a particular political party. This identification shapes political behavior, influencing voting patterns, issue priorities, and perceptions of candidates. It reflects a combination of factors, including personal values, socialization, and demographic characteristics. Strong party identification can lead to partisan bias, where individuals favor their party over competing viewpoints, affecting public discourse and policy debates. Furthermore, it plays a role in shaping political landscapes and electoral outcomes, as it often determines party loyalty and engagement in political processes, contributing to overall political polarization.
