The map shows Clinton cutting a wide swath of blue through the western part of Gwinnett, taking most precincts in the Norcross and Lilburn areas (some of the county's most diverse neighborhoods) then stretching all the way through the heart of Lawrenceville.

Clinton also won in all of the county's precincts with a majority of black voters, a significantly sized pocket on Gwinnett's southern tip.

The top 5 Gwinnett neighborhoods for Clinton:

Martins E (Ferguson Elementary, 1755 Centerview Drive, Duluth): 88 percent

Pinckneyville Q (Beaver Ruin Road Baptist Church, 1200 Beaver Ruin Road, Norcross): 85 percent

Pinckneyville J (John Wesley United Methodist Church, 5320 Jimmy Carter Blvd., Norcross): 84 percent

Martins D (Sweetwater Middle School, 3500 Cruse Road, Lawrenceville): 83 percent

Pinckneyville N (Landmark Church, 3737 Holcomb Bridge Road, Norcross): 81 percent

Trump, meanwhile, dominated the northern and far eastern parts of Gwinnett like Buford and Dacula and Hoschton — in many cases, the county's whitest and most rural areas.

The president-elect also painted a significant strip of the county's southern half red.

The top 5 Gwinnett neighborhoods for Trump:

Duncans C (Hamilton Mill UMC, 1450 Pine Road, Dacula): 75 percent

Duncans B (Duncan Creek Elementary School, 4500 Braselton Highway, Hoschton): 73 percent

Duncans D (Hamilton Mill Christian Church, 3809 Sardis Church Road, Buford): 72 percent

Duncans A (12 Stone-Hamilton Mill, 3858 Braselton Highway, Buford): 72 percent

Pucketts A (Bogan Park Community Center, 2723 N. Bogan Road, Buford): 70 percent

Gwinnett first became a majority-minority county — meaning non-white residents account for more than half of the population — in 2010. That wasn't nearly enough, however, to turn the county Democratic during 2012's presidential election.

Mitt Romney took 57 percent of Gwinnett's votes that year.
