From 2014 to 2020, the number of state legislative primaries in North Dakota with more than one candidate ranged from four to six. This year, the number of contested primaries rose to 24, a 300% increase from 2020. This represents 18% of all possible primary contests.

Of those candidates involved in primaries, 27 are incumbents, representing 37% of incumbents seeking re-election, the largest such percentage since 2014. As a result of redistricting, two incumbents—Sens. Robert Fors (R) and Randy Lemm (R)—were drawn into the same district, setting up an incumbent versus incumbent primary.
