Primary elections
Primary elections were held on June 26, 1956.
The Nonpartisan League, which had existed in the state since 1915, had been a influential coalition within the state. Though it primarily ran candidates under the Republican Party banner, there were growing divides between conservative and liberal factions of the league. After the rival factions endorsed competing presidential campaigns in 1952, the division became permanent. During the March 1956 League convention, the party voted 173 to 3 to file its candidates with the Democratic party. In May 1956, the Democratic Convention accepted the Nonpartisan League's candidates and adopted its platform, fully unifying the two parties into one and creating the North Dakota Democratic-Nonpartisan League Party. While the party organization merged with the Democrats, the conservative factions of the League joined the Republican party, shifting the state into the modern two-party system.
