"Only real issue being reported now," county spokesman Joe Sorenson wrote in an email early Tuesday evening, "is that a large number of people are voting out of precinct, and rather than going to their home precincts, they are demanding to vote provisionally."

"The complaints also point to deputies in full uniform and/or in patrol cars engaged in political campaigning."
But Forsyth Sheriff's spokesman Maj. Rick Doyle said the office hasn't received reports of deputies dressed in campaign attire and that they aren't allowed to wear political paraphernalia with their uniform. They also are not allowed to campaign on the job.

10:29 a.m.: "I'm pleased to say all the polls opened on time and on schedule," Fulton elections director Richard Barron told The AJC. "We're expecting 70 percent turnout." The previous early voting record in 2012 was 152,562. When absentee ballots come in, Barron said he expects the early vote will be about 284,000. "It's a major accomplishment for us," he said. "Early voting worked in our favor. We're pleased that our residents listened. Our hope is that today's voters also will be patient if they have a wait." Barron also addressed reports of inoperable voting machines at Therrell High in southwest Atlanta. "There seems to be a rumor that isn't true," he said. "The poll manager had to reset express polls two different times. They've already processed more than 300 voters today. Right now, she's processing voters. She's processing voters as fast as she can. We don't want to see anybody leave because of equipment malfunction. We do encourage them to go back. We probably received the fewest emails and complaints since I've been here. I'm not going to do any premature celebrating just because the first three hours have gone smoothly, but I am happy."
10:25 a.m.: The Winnona Park precinct in the City of Decatur is reliably Democratic and that has been on display this morning with the number of women showing up to vote in pantsuits, the adopted emblem of Hillary Clinton supporters.
