Why do voters vote inline with their political party and not vote inline with what benefits them more?

Voters often align with their political party due to a combination of identity, socialization, and ideological beliefs that shape their views and values. Many individuals feel a sense of loyalty to their party, viewing it as a reflection of their identity, which can override personal interests. Additionally, party affiliation can influence perceptions of issues, leading voters to prioritize party platforms over specific benefits. This phenomenon can be reinforced by social and cultural factors, including family, community, and media influences that promote party loyalty.
