Senate terms are staggered so approximately one third of the chamber is up for election every two years, shaping the legislative agenda and committee composition.

Why Senate Class Matters
Senate class (Class 1, 2, or 3) indicates which group a senator belongs to based on term length. Only one class is up for election every two years, ensuring continuity and institutional memory. For example, Class 1 seats are contested in presidential election years, while Class 3 seats are contested in midterm years. Knowing a senator’s class helps you anticipate when their seat will next be on the ballot and which elections affect their reelection prospects.
How to Interpret This List
- Check the term expiration year to see when a seat will be contested next.
- Note party affiliation to understand the state’s current delegation balance.
- Review updates after special elections, resignations, or appointments, which can shift representation between elections.
