Many legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber.[3] The chambers not up for election either hold regularly scheduled elections in odd-numbered years, or have four-year terms and hold all regularly scheduled elections in
presidential midterm election years.
