With Democrats projected to win at least one of the two Georgia Senate runoff races, they are inching closer to keeping Republicans from holding on to control of the upper body of Congress.

Democrat Raphael Warnock is projected to defeat Sen. Kelly Loeffler, R-Ga., according to Fox News' Decision Desk early Wednesday.

The focus now shifts to the second race between Sen. David Perdue and Democrat Jon Ossoff, who are locked in a tight race.

Here are some key takeaways after Tuesday's election:

1. Senate control for Democrats is within reach

With Warnock's projected victory, Democrats are one win away from control of the Senate, making it more likely that President-elect Joe Biden would be able to pass his agenda through both the House and Senate. If Perdue prevails over Ossoff, Republicans would be able to foil many of the White House's plans.

According to Fox News Voter Analysis, voters clearly saw the Georgia runoffs as a battle for control of the Senate. Most said which party controlled the Senate was an important factor -- if not the single most important factor -- to their vote.

The stakes couldn't have been higher in the dual runoff elections on Jan. 5, Senate Judiciary Committee Chairman Lindsey Graham, R-S.C., told "Hannity" in November.

Graham said a Democratic majority in the Senate would create what he called the "trifecta from hell" in all the key positions of power, a reference to Biden, House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer.
