People were lined up at the door of the Macon-Bibb County Board of Elections office before it opened Tuesday morning, waiting to register.
More than 100 people had done so before the office closed at 5:30 p.m., but the final tally wont be available till later this month, said Jeanetta Watson, elections secretary at the office.
The final surge in registrations could push Bibb Countys total past 87,000. Before the 2008 general election, there were 81,659 registered voters.
As of Monday, there were 78,529 voters registered in Houston County, said JoAnn Shipes, the countys election supervisor. She, too, said it would take some time to get all the voter cards put in the system.
Just because today is the last day doesnt mean everything will be entered today, she said.
The office has to collect the cards from multiple locations, such as satellite election offices, as well as the state before everything can be entered.
Houston had 71,786 voters registered for the last presidential election.
