who elects members to the united states 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.
United States Senate Article I, Section 3, of the Constitution, sets three qualifications for senators: (1) they must be at least 30 years old; (2) they must have been citizens of the United States for the past nine years or longer; and (3) they must be inhabitants of the states they seek to represent at the time of their election. The age and citizenship qualifications for senators are more stringent than those for representatives. In Federalist No. 62, James Madison justified this arrangement by arguing that the "senatorial trust" called for a "greater extent of information and stability of character."
