On October 20, U.S. District Court Judge James A. Teilborg of Arizona granted an injunction, forbidding Coconino County election officials from interfering with one particular voter, or any voter, who wants to wear a Tea Party T-shirt to the polls on November 2, 2010. The voter who brought the lawsuit had been told she had to cover up her shirt, when she voted at the August 2010 primary and also when she voted at a local election in May. She sued on September 20. See this story. The case is Wickberg v Owens, cv10-8177-PHX.
Although the state law against electioneering at the polls stands, the judge construed the law to only include clothing that says something specific about a candidate or a ballot measure that is on the ballot at that election. There is no Tea Party listed on the Arizona ballot.
