A swing state (also, battleground state) in United States presidential politics is a state in which no candidate has overwhelming support, meaning that any of the major candidates have a reasonable chance of winning the state's electoral college votes. Such states are targets of both major political parties in presidential elections, since winning these states is the best opportunity for a party to gain votes. Non-swing states are sometimes called safe states, because one candidate has strong enough support that they can safely assume they will win the state's votes.
