Challenges to the conduct of the Aug. 2 election may have reached a peak Tuesday, July 24. The Shelby County Election Commission admitted a “limited number” of voters in some precincts got early voting ballots that included the wrong district races. Their work on their voter database to include the new boundaries for state legislative and congressional districts approved in Nashville in February began just four days before the end of the early voting period in advance of the Aug. 2 election day. And sometime during the day Tuesday, City Attorney Herman Morris filed a lawsuit in Nashville Federal Court challenging state election officials on their decision not to honor photo library cards as a legal form of photo identification required by state law to vote. The lawsuit alleges violations of the U.S. Constitution including the equal protection clause.
