President Donald Trump and Democratic challenger, Joe Biden, worked to strengthen their campaigns in primary contests across Georgia and West Virginia on Tuesday that tested whether the protest movement sweeping the streets across America would translate to the voting booth.

Biden in particular hoped to emerge as the prime beneficiary of energy from the African American community and its white allies who have held massive protests for more than a week.

The former vice president's path to the presidency was already focused on maximizing black turnout and expanding his alliance with white suburbanites and city dwellers, young voters, Asian Americans and Latinos. Trump, meanwhile, hopes to demonstrate strength among his base of white voters in small towns while holding his own in metro areas.

Georgia, which has emerged as a potential battleground state this fall, offers the clearest test for those two paths. The state is also holding a Senate primary on Tuesday, with congressional primaries happening in states including Nevada and South Carolina.

The biggest question is whether Biden can generate enough excitement among the nation's black community to put states like Georgia legitimately in play this fall.

In an interview on the eve of Tuesday's primaries, NAACP President Derrick Johnson downplayed the significance of Biden’s early advantage among black voters.

“You can put a truck driver on the ballot against the current president, and you’re going to get a similar result in terms of support. What’s really at issue here is enthusiasm,” Johnson said in an interview. “Are individuals across the country energized enough behind his vision to turn out to vote? That’s the question that’s on the table.”

At an elementary school north of Atlanta in Roswell, about 60 voters were lined up outside Tuesday morning. Layla Cantlebary, 39, said she arrived at the polling site about 15 minutes before it opened and waited more than an hour to cast a ballot.

“I always vote in primaries, but the political times that we’re having right now, or the moment that we’re having is scary, and it’s very important I feel like to voice our concerns through our voting,” said the self-described liberal. “With all the civil unrest, it just underscores the importance of coming out and voting for somebody who you feel is going to lead the country to a better place than we are in currently.”

While there was no real competition for each of the presidential candidates on Tuesday, Georgia is a must-win for the Republican president in November. And Trump’s campaign has behaved accordingly.

The president’s political operation never left Georgia after 2016. His spokeswoman Savannah Viar said the campaign has 85 staffers on the ground, considerably more than Democrats’ current crop, which includes six workers focusing on voter protection and more than 40 field workers contacting voters.

Both sides say their staffs will grow.

“The national stage finally shows what we’ve been saying for some time: that we are a battleground,” said Georgia Democratic Party Chairwoman Nikema Williams, arguing that the state’s growing, diversifying population, coupled with Trump’s turbulent presidency, portends a tipping point.

GOP pollster Whit Ayres added this warning for Trump, who carried the state by 5 percentage points in his first general election: “If he doesn’t win Georgia, then it’s pushing a landslide nationally.”

The state offers a wide swath of rural and small-town counties where Trump remains immensely popular among white majorities. His margins there four years ago helped overcome his deficits in metropolitan areas, including losses in key suburban Atlanta counties that hadn’t been won by Democrats in a presidential election in four decades.

But Democrats point to their successes since — and to voter registration trends that show a swath of new voters in the metropolitan areas where the GOP has struggled.

Democratic Rep. Lucy McBath flipped a suburban Atlanta congressional district in 2018. Democrats nearly flipped a neighboring district and forced a GOP retirement shortly afterward. And Stacey Abrams, now listed among Biden’s potential running mates, narrowly lost the 2018 governor’s race by 1.4 percentage points.

Biden’s campaign manager, Jen O’Malley Dillon, mentions Georgia along with Arizona and Texas as the next three states that Democrats can flip. Still, O’Malley Dillon holds up Arizona as the best opportunity for Democrats, implicitly tamping down expectations in Georgia.

Early voting trends offer both parties talking points.

Because of the COVID-19 pandemic, Georgia’s Republican secretary of state sent applications for absentee ballots to every registered voter. By Monday, at least 1.27 million people had already voted, according to Ryan Anderson, an Atlanta data analyst who examines state elections records for his independent website, GeorgiaVotes.com. That figure dwarfs the early vote in the 2016 primary.

Still, Johnson wasn't sure what effect, if any, the protests might have on Tuesday's contests.

“I don’t want to make any predictions,” he said. ”But we definitely will be watching to see how all of this will translate."
