For how long is a U.S. Senator elected?

A U.S. Senator is elected for a term of six years. This duration allows Senators to focus on long-term policies and issues rather than being in constant campaign mode, as they do not face re-election every two years. The longer term is designed to provide stability and continuity in the Senate. Each Senator can be re-elected for additional terms, so there is no limit to the number of times they can run, which can lead to many years of service. This six-year term structure is part of the larger framework of the U.S. government, aimed at ensuring that those in the Senate have the time to develop expertise and relationships necessary to effectively carry out their legislative duties.
