For how many years are U.S. Senators elected?

U.S. Senators are elected for a term of 6 years. This duration is established by the U.S. Constitution, specifically in Article I, Section 3. The longer term allows Senators to focus on legislation and serve their constituents without the immediate pressures of frequent elections. This structure is intended to provide stability and continuity within the Senate, as well as to encourage Senators to take a longer-term perspective on their legislative duties, which is different from the shorter terms of members of the House of Representatives, who serve 2-year terms. The design aims to maintain a degree of experience and legislative expertise in the Senate, contributing to the overall functionality of the legislative branch.
