On June 15, Iowa state officials removed three Libertarians from the ballot. They include the party’s nominees for Governor, Lieutenant Governor, and U.S. House in one district. See this story.
No one questioned the validity of the signatures. Approximately 8,000 had been gathered for the ticket of Governor and Lieutenant Governor. The candidates expect to sue to reverse the decision.
The party is on for one other U.S. House seat, and for U.S. Senate.
