The U.S. presidential election is a process where citizens vote to choose their leader, the President of the United States. This election occurs every four years, and candidates from major political parties, like the Democratic Party and the Republican Party, campaign to win the support of voters. During the election, people participate in primaries and caucuses to select their party's nominee. The final election day is usually in November, when voters cast their ballots. The candidate with the most votes in the Electoral College ultimately becomes the president, shaping the country's future for the next four years.
