Explanation:

The Senate of the United States is one of the two chambers of the United States Congress. Each of the 50 states is represented in the Senate by two senators. They each represent the entire state and are determined there by a general majority vote. Until the adoption of the 17th Amendment in 1913, the members were elected by state parliaments. The senators officiate six years. They are divided as evenly as possible into three classes (currently two classes each with 33 senators and a class with 34 senators), which in turn are redefined every two years through elections. As a result, approximately one-third of the Senate will be re-elected at each election. Since the District of Columbia and the external areas are not states, they are not represented in the senate. Unlike the House of Representatives, there is no symbolic representation by non-voting delegates.
