UNION CITY, Ga. Additional police will be present at the election headquarters in Fulton County, Georgia, this year just because of whats going on, LaShandra Little, voter education and outreach manager for the county, said euphemistically during a facility tour Monday.

Just hours before Election Day, theres a lot going on in Fulton County. Fulton is Georgias most populous county and a Democratic stronghold that could provide the blue votes necessary to put Vice President Kamala Harris over the top, both in the state and, potentially, overall.

This is also the countys first year using a mammoth new Election Hub facility. It takes up 400,000 square feet of a 1-million-square-foot warehouse in Union City, just outside Atlanta. And on Election Day eve, it was buzzing with anticipation.

The Election Hub facility is imposing, looking from the outside like an Amazon warehouse. Inside, election machines are lined up in lengthy rows and election workers operate in neon vests and VOTE T-shirts. Throughout the building, they are organizing voter registration application forms, wheeling tabulator machines into place, and systematically opening the envelopes carrying absentee ballots a step called pre-processing that, at least in some states , allows the counting to proceed much more quickly Tuesday. Near a section reserved for election observers, a studio-apartment-sized room is walled in glass on all four sides. Inside sit the computers that will tally the countys results.
