The New Hampshire primaries are on September 11. According to this story, there will probably be a contested Libertarian Party primary for Governor. It is likely that both Jiletta Jarvis and Aaron Day will seek the party’s nomination.
The Libertarian Party also had its own primary in 1992, 1994, and 1996, but there was no contest for the gubernatorial nomination in those years. New Hampshire elects a Governor every two years. The party needs to poll 4% for Governor this year to retain its qualified status.
This was not the LPNH’s first contested primary for governor. The party won major party status in New Hampshire in 1990, and there was a contested Libertarian primary for governor in 1992, 1994 and 1996.
In 1992, Miriam Luce (winner) ran against Calvin Warburton. In 1994, Steve Winter (winner) ran against Calvin Warburton and Clarence Blevins. In 1996, Robert Kingsbury (winner) ran against Clarence Blevins.
