Democrat and former Atlanta Mayor Keisha Lance Bottoms is projected to win the Georgia gubernatorial race -- becoming the first Black female governor not just in Georgia but in the nation.

She is projected to defeat Republican Rick Jackson over the seat held by term-limited Republican Gov. Brian Kemp.

Democratic Connecticut Gov. Ned Lamont is projected to defeat Republican challenger Ryan Fazio.

With Democrat Roy Cooper projected to flip the critical battleground Senate seat in North Carolina, here's how he pulled it off, according to preliminary ABC News Voter Poll findings:

Race: Black voters made up roughly 1 in 6 Senate voters and about 9 in 10 voted for Cooper. The three-quarters of the state's electorate that are white were roughly divided between Cooper and Republican challenger Michael Whatley.

Education: Early ABC News Voter Polls find non-college-educated voters were evenly divided between Cooper and Whatley and suggest Cooper improved among college-educated voters, winning this group by over 30 percentage points.

Party: Cooper fared particularly well among independent voters, with about 6 in 10 of these voters backing him and roughly one-third voting for Whatley, according to early ABC News Voter Polls.

Age: Early ABC News Voter Polls find that Cooper won young voters ages 18 to 29 by about 58 percentage points.
