Michigan holds major party primaries on August 7. State Senator Nancy Cassis, a write-in candidate in the Republican primary for U.S. House, 11th district, is leading in the polls, even though she has an opponent who is listed on the ballot. See this story.
The Michigan Democratic Party, and also the Republican opponent of Senator Cassis, both filed complaints with election officials to stop her campaign from handing out rubber bracelets near the polls, reminding voters how to spell her name. But those complaints did not prevail. See this story. Thanks to Thomas Jones for the link.
