In United States politics, a swing state (also known as battleground state, toss-up state, or purple state) is any state that could reasonably be won by either the Democratic or Republican candidate in a statewide election, most often referring to presidential elections, by a swing in votes. These states are usually targeted by both major-party campaigns, especially in competitive elections.[1] Meanwhile, the states that regularly lean to a single party are known as "safe states" (or more specifically as "red states" and "blue states" depending on the partisan leaning), as it is generally assumed that one candidate has a base of support from which a sufficient share of the electorate can be drawn without significant investment or effort by the campaign. In the 2024 United States presidential election, seven states were widely considered to be the crucial swing states: Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania, and Wisconsin.[2][3]
Due to the winner-take-all method that most states use to determine their presidential electors, candidates often campaign only in competitive states, which is why a select group of states frequently receives a majority of the advertisements and candidate visits.[4] The battlegrounds may change in certain election cycles and may be reflected in overall polling, demographics, and the ideological appeal of the nominees.
