I'm in Gwinnett too. Very heavy turnout in my area. A gentleman in line said he had been voting at that precinct for 25 years and has never seen it that heavy. I believe him!
I vote near Collins Hill HS in Gwinnett County. We've been here since the early 80s. NEVER seen lines like this in Gwinnett. Can't attribute the lines to population growth either -- this area is about 95% built out. So I see this as HEAVY HEAVY HEAVY turnout in 'Pub area.
