U.S. Senators are elected for a six-year term. One third of the Senators are up for election every two years.
1/3
Every two years, in every even-numbered year, about one third of all Senate seats, representing about two thirds of all of the states, come up for election. No one state elects both of their U.S. Senators in the same years, except in some cases when a special election is required to fill a vacancy. Senators whose seats come up for election in 2014 are known as Class 2 Senators, Senators whose seats come up for election in 2016 are known as Class 3 Senators, and Senators whose seats come up for election in 2018 are known as Class 1 Senators.
Senators are elected into power the same way the president is. When the Senator in your area is up for re-election there will be one held on the same day as the presidential election.
Senators. Up till then, the state legislatures elected Senators. Now the people of the states would.
Senators serve terms of 6 years. Terms are staggered, so that only about 1/3 of senators are up for election any given year. •This way, of the Senate's seats are never up for election at the same time. •This creates 3 layers of experience: newly elected -Freshman Senators, -Mid-term Senators, and -Veteran Senators.
In any one election year the portion of senators elected is about one third. Every two years about 33 or 34 states have senatorial elections.
1/3 of the Senators' terms expire in every 2 years, but since there are 50 states with two Senators apiece and that does not divide by 3, in two election years 34 Senators are elected (or re-elected) and in the third year the remaining 32.
1/3 of Senate seats are up for election every two years.
The senate and I believe the house also do a "staggered" election. A senator's term is 6 years but not all senators are up for election at the same time. Senator A is up for election this year while senator B is up in 2009. both are serving 6 year terms but the start of the terms are not the same.
Elections are every 2 years but senators serve for 6 years so to even this out only 1/3 are elected each vote time.
Senators serve six year terms and they can be re-elected to indefinite terms. Some Senators end up serving for life.
Missouri has 34 state senators and districts. State Senators of Missouri serve four-year terms, but half of the seats are up for election every two years.
