North Dakota is the only state in which there are no candidates on the November 2012 ballot for state legislature, other than the Democratic and Republican Party nominees.
Even though there are four qualified parties on the ballot in North Dakota, qualified parties in that state cannot run legislative candidates unless approximately 10% to 15% of all the primary voters choose to vote in that party’s primary. North Dakota has open primaries, so a voter is free to vote in any party’s primary, but the idea that such a large share of voters would ever choose a minor primary ballot is unrealistic. In no state with open primaries in the last forty years is there any instance in any state when more than 6% of the state’s primary voters chose a minor party primary ballot.
North Dakota also has very stringent petition requirements for independent candidates for the legislature. They need a petition signed by 2% of the population of the district, including children and aliens. The typical state legislative district in North Dakota only has 6,700 voters in a presidential general election, and in the typical district an independent for the legislature needs 250 signatures. If a minor party nominee does decide to qualify using the independent procedure, he or she is not permitted to have a ballot label other than “independent.”
Even Georgia this year has one independent on the ballot for state legislature. He is Rusty Kidd. He is an incumbent running for re-election, and under a unique Georgia law, independent candidates don’t need a petition if they were elected as an independent in the last regularly-scheduled election.
