This section provides an overview of media reactions to the North Dakota state legislative Republican primaries.[1] Selected articles are presented as a jumping-off point for deeper exploration of media coverage and as an overview of narratives that have emerged surrounding the elections.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. A primary election is also sometimes used to choose convention delegates and party leaders; however, these selection processes can vary from state to state and party to party within a state. In North Dakota, precinct, district, and state party officials are selected at party caucuses and conventions, not at the state-administered primary election. Primaries are state-level and local-level elections that take place prior to a general election. North Dakota utilizes an open primary system, in which voters do not have to be members of a party to vote in that party's primary.[2][3]
For information about which offices are nominated via primary election, see this article.
In North Dakota, voting hours at polling locations vary by county. According to statute, all polls must open between 7:00 a.m. and 9:00 a.m. local time, and they must close between 7:00 p.m. and 9:00 p.m. North Dakota is divided between the Central and Mountain time zones. Hours for specific polling places are available online through the state's Polling Place Search. Anyone in line when the polls close must be allowed to vote.[4][5]
North Dakota is the only state that does not require voter registration.[6][7]
| “ | Although North Dakota was one of the first states to adopt voter registration prior to the turn of the century, it abolished it in 1951. It is also worth noting that North Dakota law still provides cities with the ability to register voters for city elections.

According to the secretary of state's office, an absentee ballot applicant "without an acceptable form of ID may use an attester." The attester "must provide name, valid ID number and sign the absentee or mail ballot application attesting the applicant's ND residency or voting eligibility."[9]
North Dakota law permits counties to establish early voting.[10] As of November 2025, six of North Dakota's 53 counties offered early voting. Together, these counties contained 63 of the state's 157 Election Day polling places.[11] Learn more by visiting this website.
Early voting permits citizens to cast ballots in person at a polling place prior to an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.
Forty-seven states and the District of Columbia permit no-excuse early voting.
All voters are eligible to vote absentee in North Dakota. There are no special eligibility requirements for voting absentee.[12][13]
There is no specific deadline for applying for an absentee ballot. The completed ballot must be received by the appropriate election official by the close of polls on Election Day.[13][14]
