2018 North Dakota elections

Incumbent Democratic–NPL Senator Heidi Heitkamp ran for reelection to a second term, but was defeated by Republican United States Representative Kevin Cramer.

Though incumbent Republican Kevin Cramer had announced that he would run for re-election to a fourth term, he later decided to run for the Senate instead. Republican state Senator Kelly Armstrong defeated Democratic-NPL former state Senate Minority Leader Mac Schneider for the open seat.

Six-term incumbent Republican Secretary of State Alvin Jaeger was not re-endorsed by his party to serve a seventh term, so did not run for his party's nomination.[4] When nominated Republican Will Gardner withdrew from the general election, Jaeger collected enough valid signatures to appear on the ballot as an independent. No candidate appeared on the ballot with the label of Republican.[5]

The incumbent defeated two challengers, including two-term Democratic-NPL state representative Joshua Boschee.[5]

Governing magazine projected the race as being a likely victory for Jaeger.[6]

Incumbent Republican Attorney General Wayne Stenehjem won re-election against his Democratic-NPL challenger, trial attorney David Thompson.

All North Dakota voters faced partisan races for Agriculture Commissioner, Tax Commissioner, one full term seat and one partial term seat on the Public Service Commission, and a nonpartisan ten-year term as Justice of the Supreme Court

24 seats in the North Dakota Senate and 48 seats in the North Dakota House of Representatives were up for election. Voters in all odd-numbered districts had those races on their ballot.

Voters faced four measures placed on the ballot by petition.[1] They passed Measure 1, which will establish government ethics rules and an ethics commission; the Secretary of State approved it for the ballot on July 24.[8] They also passed Measure 2, which removes language in the state constitution currently guaranteeing all citizens to right to vote and replaces it with language banning non-citizens from voting; it had been approved on August 10.[9] Measure 3 would have legalized the recreational use of marijuana, but was not passed.[10] They did, however, approve Measure 4, which establishes personalized vehicle plates for volunteer emergency responders.[11][12][13]
