Ohio is holding primaries this year for six political parties, including the Constitution, Green, Libertarian and Socialist Parties. Candidates in those primaries need 25 signatures to get on the primary ballot. Ty Collinsworth is a college student trying to run in the Green Party primary for state Representative in the 92nd district, in Athens. A Democrat has filed a challenge to Collinsworth’s petition. See this story, from the Jesse Hathaway blog.
The story says that members of one party do not have the legal right to file a petition challenge in the primary of another party. The story also says that the challenger identified himself as a Democrat when he filled out an application to vote absentee in the 2008 primary. Thanks to Bill Van Allen for the link.
