How many U.S. Senators are there?

The total number of U.S. Senators is 100 because the United States Senate is composed of two Senators from each of the 50 states. This structure was established to ensure equal representation of each state in the federal legislature, regardless of population size. Each Senator serves a term of six years, and the Senate is one half of the United States Congress, the other half being the House of Representatives, which has a larger number of members based on state populations. Thus, the answer of 100 correctly reflects the equal representation designed in the Senate's format.
