How often are congressional elections held?

Congressional elections are held every two years to maintain a balance of legislative power and ensure that representatives remain accountable to their constituents. The two-year election cycle applies specifically to the House of Representatives, where all 435 members are up for election every even-numbered year.

In addition to the House, approximately one-third of the Senate is also up for election every two years, since Senate terms last six years. This frequent cycle allows for a more dynamic responsiveness to the public's changing priorities and concerns, reflecting the democratic principles of representation.

This setup contrasts with other election cycles, such as presidential elections, which occur every four years, and is essential for the functioning of a representative democracy, ensuring that the legislative body does not become disconnected from the will of the electorate.
