The Senate consists of 100 members, with each of the 50 states represented by exactly two senators serving staggered six-year terms. Article One of the Constitution established this equal state representation in 1789, giving states with vastly different populations identical Senate power. California''s 39 million residents elect two senators, the same number as Wyoming''s 580,000 residents, creating significant disparities in representation per capita. Senators are divided into three classes with terms staggered so a different class faces election every two years, ensuring institutional continuity. Class 1 senators were last elected in 2024, Class 2 in 2020 (up for reelection in 2026), and Class 3 in 2022. This structure means voters in each state elect one senator every three years on average. The equal state representation was a compromise at the Constitutional Convention between large and small states, contrasting with the House''s population-based representation.
