Filing has now closed for Missouri primaries, which are held on August 3 this year. In the U.S. House race, 9th district, two Republicans filed, and two Libertarians, but no Democrats and no one from the Constitution Party. See this story.
To see the complete candidate list, see the Missouri Secretary of State’s web page here. There are two statewide races in Missouri this year. The two qualified minor parties, Libertarian and Constitution, will each have a U.S. Senate nominee. In the other statewide race, for Auditor, there will be a Libertarian, but no one from the Constitution Party. The Libertarian Party must poll 2% in one of the two statewide races or it will lose its qualified status. The Constitution Party need not worry about polling 2% for a statewide race in 2010, because it polled 2% for one of the statewide races in 2008, and in Missouri, when a party passes the vote test, it remains on for the next two elections.
The Green Party, which is not ballot-qualified, is petitioning for party status this year. That petition needs 10,000 signatures and is due in late July. If the petition drive succeeds, the Green Party will be able to nominate by convention for any partisan race. In Missouri, the name of the Green Party is “Progressive Party.”
