In the context of U.S. elections, "swing states" refer to states where no single party consistently holds a majority, making them critical battlegrounds during elections. Candidates often focus on these states, as their electoral votes can determine the outcome in tightly contested races. Swing states tend to reflect a mix of demographics and political ideologies, leading to fluctuating voting patterns. Campaign strategies are tailored to appeal to the specific concerns and values of voters in these states, illustrating their pivotal role in shaping election results.
