Partisan change refers to shifts in political party alignment among voters, often influenced by social, economic, or cultural factors. This change can lead to significant electoral outcomes, as individuals may switch their support from one party to another, impacting the overall balance of power in government. Such changes can occur during elections or over longer periods, reflecting evolving public opinions and priorities. For example, demographic shifts or major events, like the Great Recession or civil rights movements, can drive voters to reassess their party affiliations, resulting in a realignment of political loyalties across the electorate.
