How many total US senators are there?

The total number of US senators is 100 because the United States Senate is composed of two senators from each of the 50 states. This structure ensures equal representation for every state, regardless of population size, and has been a fundamental aspect of the legislative branch since the founding of the country. Each senator serves a six-year term, and the Senate plays a crucial role in the federal government, including the approval of treaties and federal appointments, as well as serving as a check on the powers of the House of Representatives.
