Statewide elections in North Dakota occur every two years. Most executive offices and all legislators are elected to four-year terms, with half the terms expiring on Presidential election years, and the other half of the offices expiring on mid-term election years.
North Dakota is the only state without a voter registration process. Any person over the age of 18 who has lived in a precinct for three or more months may vote in local, state, and federal elections without registration. In order to vote, however, a person must bring identification of a type pre-selected by the North Dakota Secretary of State. For the 2016 election[update], this list includes a North Dakota driver's license, non-driver's ID card, tribal government issued ID card, or an identification card provided by a North Dakota long-term care facility. Neither a United States Passport nor a North Dakota College- or University-issued ID card are accepted, and North Dakota does not offer provisional ballots to those who do not have an acceptable form of identification.
Since the 1972 presidential election, North Dakota has been able to send three electors to the Electoral College, who the voters pick in a first-past-the-post winner-take-all popular vote.
Like all US states, North Dakota must send two Senators to the United States Senate. North Dakota's two senators are in classes 1 and 3. Senators John Hoeven and Heidi Heitkamp currently serve the state; Hoeven was elected in 2010, and Heitkamp in 2012, both to six-year terms.
Since 1972, North Dakota has had a single seat in the United States House of Representatives; Kevin Cramer currently fills the seat, the term for which expires every two years.
