On June 13, Jonathan Lines, chair of the Arizona Republican Party, filed a lawsuit in state court, claiming that the petition to put Kevin McCormick on the Libertarian August primary ballot for Governor does not have enough valid signatures. Lines v McCormick, Maricopa County Superior Court.
The Secretary of State and county election officials had determined that McCormick’s petition is valid. See this story at Independent Voters Network, which has a long facebook thread between McCormick and many people who signed his petition.
No one has challenged the petition submitted by the Libertarian candidate for U.S. Senate.
