All told, Gwinnett County has 430,954 voters it considers "active" — meaning that more than 38 percent of the county's predicted voters have already cast their ballots ahead of Tuesday's election.
In addition, Sorenson said more than 7,000 absentee ballots sent out had not yet been returned.
Early voting turnout has been high since Day 1 for Gwinnett, which had to open two satellite locations a week earlier than expected to accommodate the huge crowds at its elections office.
Among the more high-profile Gwinnettians to vote early was State Rep. Buzz Brockway — a Republican who announced on Facebook early Monday that he'd cast a "very reluctant vote for Donald Trump."
No early voting will be held Monday. Polls throughout Gwinnett County will be open from 7 a.m. to 7 p.m. Tuesday. Visit the Secretary of State's website to find your polling place.
The U.S. Department of Justice announced Monday that Gwinnett will be one of three counties in Georgia where it will deploy federal poll monitors, which are tasked with assuring compliance with federal voting laws. Fulton and Hancock counties will also have poll monitors Tuesday.
