WASHINGTON — Stacey Abrams easily defeated Stacey Evans in a Georgia Democratic gubernatorial primary Tuesday that attracted national attention, according to a projection by the Associated Press.

Now, Abrams will attempt to make history by becoming the nation's first black female governor in November — and her state's first woman governor — by winning the general election in a state that Republicans still dominate.

The GOP had their own contentious gubernatorial primary Tuesday, which remains too close to call. If none of the five Republican candidates clears the 50 percent threshold, they'll head to a July 24 runoff, giving Abrams a head start.

 Democrats' "Stacey v. Stacey" primary was being closely watched because it was seen as a microsom of a wider debate Democrats have been engaged in since President Donald Trump's upset election in 2016: Should the party prioritize winning back white swing voters or focus on mobilizing its burgeoning coalition of minorities and young people?

Abrams, the former minority leader of the Georgia Statehouse, is a rising star in her party thanks to her years-long work trying to turn the state blue by mobilizing Democratic-leaning residents who don't typically turn out to vote.

Evans, who is white, was raised by a teenage mother in the rural northwest corner of the state and had vowed to win over moderates in the general election.

While Evans fit the mold of candidates that Democrats have historically nominated in the South, black women have been demanding more representation in the party, noting they have been its most loyal voters.

"Stacey Abrams won this election because she reached out and engaged communities of color, particularly black voters, on the issues that they care about," said Adrianne Shropshire, the executive director of BlackPAC, which supported Abrams. "This historic victory is a model for candidates all across the country."

In Georgia, women of color make up 23 percent of the population, but only 8 percent of officeholders, according to the Reflective Democracy Campaign.

The state has been trending in Democrats' direction as its population diversifies, with Hillary Clinton coming within 5 percentage points of Donald Trump in 2016.

But Republicans still rule the Peach State and Abrams will surprise a lot of people if she wins.

"Stacey Abrams is expanding the limits of the possible in American politics," said Aimee Castenell, a spokesperson for the progressive Working Families Party, which backed Abrams.

Georgia Lt. Gov. Casey Cagle was leading a crowded field of Republican rivals heading into election day, with Secretary of State Brian Kemp in second, according to polls.

The GOP primary earned headlines as the candidates tried to one-up each other on who would be toughest on immigration.

One of Cagle's ads featured images of MS-13 gang tattoos and guns being fired at the screen, Kemp pledged to round up undocumented immigrants in his "big truck," while a third contestant, state Sen. Michael Williams, outfitted an entire "deportation bus" for the purpose.

Gov. Nathan Deal, a Republican, is term-limited.

Primaries were also held Tuesday night in Kentucky and Arkansas, while Texas had its primary runoff election for races where no one won a majority during the first round in March.
