Longtime Congressman John Conyers of Michigan doesn’t have enough signatures to appear on the Aug. 5 primary ballot, an elections official announced Tuesday. Conyers’ nominating petitions were insufficient, Wayne County Clerk Kathy Garrett said in a statement. It follows her report last week finding Conyers more than 400 signatures short of 1,000 needed. Garrett said Tuesday that he had 592 valid signatures after challenges. The 84-year-old Detroit Democrat was at risk because officials believe several people who signed his petitions do not appear to have been registered voters or had registered too late. Fox News.
