Step 1 : Introduction to the question "A person elected to the U.S. Senate serves a term of how many years?"
...U.S. Senators serve six-year terms, significantly longer than the two-year terms of members of the House of Representatives. The Framers of the Constitution designed the Senate to provide stability and continuity in the federal government. To maintain that continuity, Senate elections are staggered so that only about one-third of the 100 seats are up for election every two years. Each state elects two senators, regardless of its population or geographic size. This system has remained in place since the Constitution was adopted in 1789.
