Again? Georgia Senate runoff winners may not be known tonight

It could be déjà vu in Georgia, as the state on Tuesday holds twin Senate runoff elections that will determine if the Republicans keep their majority in the chamber or if the Democrats control both houses of Congress as well as the White House.

Two months after the presidential election results in Georgia and a handful of other key battleground states went into overtime, with the races not called in some cases until four days after Election Day, there’s a good chance it could happen again in the runoff contests.

"We can expect a very, very, close election," veteran Georgia based GOP consultant Chip Lake told Fox News. "An election that might be so close that we might not know who won these races on Tuesday night. It could be a few days after that until all the votes are counted."

In the general election, 4.9 million people cast ballots, shattering the Peach State’s previous turnout record.

Fast forward two months and the state’s breaking a turnout record for runoff contests.

More than 3 million people, or two-fifths (40%) of the state’s registered voters, have already cast a ballot in the runoffs, either through early in-person voting or by absentee ballot. And anywhere from 800,000 to possibly over a million people will vote on Election Day.
