National elections are events where citizens of a country vote to choose their leaders and representatives. These elections can include positions such as the President, members of the Congress, or local officials. They are typically held at regular intervals, such as every four or five years, depending on the country's laws. During national elections, voters express their preferences through ballots, which can be cast in person, by mail, or electronically. The results determine who will hold office and influence government policies. National elections are essential for democracy, as they allow citizens to participate in the decision-making process and hold leaders accountable.
