how many senators make up the us senate
United States Senate The composition and powers of the Senate are established by Article One of the United States Constitution.[1] The Senate is composed of senators, each of whom represents a single state in its entirety, with each state being equally represented by two senators, regardless of its population, serving staggered terms of six years; with 50 states currently in the Union, there are 100 U.S. Senators. From 1789 until 1913, Senators were appointed by legislatures of the states they represented; following the ratification of the Seventeenth Amendment in 1913, they are now popularly elected. The Senate chamber is located in the north wing of the Capitol, in Washington, D.C.
Elections in the United States The Senate has 100 members, elected for a six-year term in dual-seat constituencies (2 from each state), with one-third being renewed every two years. The group of the Senate seats that is up for election during a given year is known as a "class"; the three classes are staggered so that only one of the three groups is renewed every two years. Until the Seventeenth Amendment to the United States Constitution in 1913, States chose how to elect Senators, and they were often elected by state legislatures, not the electorate of states.
