A Senate term is six years long, so senators may choose to run for reelection every six years unless they are appointed or elected in a special election to serve the remainder of a term.
Are senators re elected every 2 years?
Senators are elected to six-year terms, and every two years the members of one class—approximately one-third of the senators—face election or reelection.
Do we elect senators every year?
Members of the House of Representatives serve two-year terms and are considered for reelection every even year. Senators however, serve six-year terms and elections to the Senate are staggered over even years so that only about 1/3 of the Senate is up for reelection during any election.
