What are swings used for in elections?

Swings in elections refer specifically to the measurement of the change in votes received by a political party or candidate between two different elections. This statistic provides valuable insights into the shift in voter support, highlighting trends or changes in public opinion over time. It allows analysts, political parties, and candidates to understand how effective their campaigns are and whether they are gaining or losing traction among the electorate.

This measurement is critical for strategizing future campaigns, as it can indicate which demographics are changing their voting patterns and how political landscapes might evolve. Understanding swings can also serve as a predictive tool for upcoming elections, helping to forecast potential electoral outcomes based on historical data.

Other options, such as assessing voter turnout or determining candidate eligibility, do not pertain directly to the concept of swings, which is focused solely on the change in vote share between elections. Additionally, analyzing electoral fraud is a separate concern that deals with integrity and security in the electoral process, not with measuring voting trends and shifts.
