From ProPublica’s Electionland:

Election officials in Gwinnett County, Georgia, have thrown out almost one in 10 of the vote-by-mail ballots cast. Officials cannot explain why, though they deny it was done out of malice. Citizens whose votes have been rejected can resubmit their ballots or vote in person, but advocates say that this puts an undue burden on voters.

There are deeper concerns that worry democracy watch dogs related to the mail ballots. The original story was broken in an article by Mark Niesse and Tyler Estep at the Atlanta Journal-Constitution. According to that article:

Because of its sizable Latino population, Gwinnett is the only county in Georgia that is federally mandated to provide elections materials in both English and Spanish. The primary election in May was the first time such materials, which include registration forms, ballots and everything in between, were used. “Gwinnett County needs oversight to ensure it does not disproportionately disenfranchise minority voters this election cycle,” Gonzalez said.

Another reason to worry about democracy in Georgia has arrived.
