What is a swing state?
A swing state - also called a battleground state - is one where neither major party has a reliable lead, making it competitive and decisive in the Electoral College.
A swing state, sometimes called a battleground or purple state, is a state where the balance of registered voters, demographic trends, and recent election results leave neither major party with a reliable advantage. Because most states predictably vote for the same party in most presidential elections, campaigns concentrate resources on the smaller group of states that could plausibly go either way.
In recent cycles, states like Pennsylvania, Michigan, Wisconsin, Arizona, Georgia, Nevada, and North Carolina have been classified as swing states. The precise list shifts over time as demographics and political alignments evolve - states that were once reliably one party can become competitive (and vice versa).
Because the Electoral College is winner-take-all in 48 states, winning a swing state by one vote earns the same electoral votes as winning it by 20 points. This math drives enormous campaign spending, advertising buys, and candidate visits to a handful of competitive states.
The swing-state landscape for 2028 will likely resemble recent cycles, but demographic shifts, economic conditions, and candidate profiles could reshape which states are truly in play.

Each state gets electoral votes equal to its congressional seats. A candidate needs 270 of 538 to win. Voters choose slates of electors who then cast the official votes in December.
270 out of 538. A candidate must win a majority of electoral votes - at least 270 - to be elected president. If no one reaches 270, the House of Representatives decides.
Yes. Because the president is elected by the Electoral College, not the national popular vote, a candidate can win more total votes nationwide and still lose the election.
