The numbers and the history show the folly of that approach. By insisting on the strategy of appealing to white Republican and moderate voters, Democrats have lost over and over again with a population that is nearly a majority of people of color — specifically, voters of color who make up nearly half of the Democratic Party membership in Georgia and nationally. Even casual observations of these numbers and trends would indicate that Democrats do not need to persuade a single Trump voter to win.

Stacey Abrams had the vision to see the value of voters that are more often than not ignored by both parties. They are young people, black people and other voters of color — all of whom are part of the 1.2 million eligible and unregistered voters in Georgia. Some 700,000 of those voters live outside the metropolitan Atlanta area. Ms. Abrams had the foresight to see those voters as an untapped electoral resource. In 2014, while serving in the leadership of the Georgia House, she founded the nonprofit New Georgia Project to register and talk to them. If we reach those voters, listen to them and register them, she argued, they will become deeply engaged in our democratic process. In other words, they will vote.

Furthermore, with the emerging voters engaged, Democrats could establish and enact an agenda beyond Atlanta. Ms. Abrams has addressed issues of racial justice, economic inequality, L.G.B.T. rights and gender discrimination in an integrated platform. Her vision for “economic mobility” directly takes on the structural barriers keeping people in poverty.

Also as part of her platform, she has advocated equal pay for women. For example, she’s proposing to provide state dollars to entrepreneurs to start local businesses, with a focus on rural and low-income communities. She advocates providing health care to the working poor by expanding Medicaid coverage as well as securing the Affordable Care Act in the state to benefit an additional half million people and create tens of thousands of jobs. It would also provide a stronger economic base in rural counties. Finally, it’s worth noting that she is boldly advocating access to obstetricians and gynecologists, is an abortion rights advocate and wants to attract medical personnel to underserved areas of the state.

The Abrams campaign has also forged a connection with these voters on the ground: She has not poured millions into trivial television and radio ads but has instead stressed face-to-face meetings. Dozens of Ms. Abrams’s campaign staffers and volunteers have been on the ground for months knocking on doors, organizing community meetings and connecting with the voters. A recent poll shows the innovation is working: Ms. Abrams is leading Ms. Evans by 20 points.
