President Trump is making a big play for black voters, who overwhelmingly rejected him in 2016.

“The White House is making a very concentrated effort to go after black voters, and I talk to people in the administration about this,” said Rob Smith, a contributor to Turning Point USA, a nonprofit which focuses on GOP advocacy on college campuses. Smith, a black, gay veteran who is backing the billionaire, says his community is going to vote based on results.

“People who either did not vote for Trump in 2016 or did not vote at all may be pulling the lever for him in 2020. I am one of those people,” said Smith.

Smith cited legislation like the First Step Act — President Trump’s signature criminal justice reform bill which creates an opportunity for thousands of federal prisoners to earn an early release — as well as opportunity zones to spur investment in poor, often minority-dominated communities, as proof the president’s promises were more than just empty words.

In November the campaign launched “Black Voices for Trump” with an advisory board that include performers Diamond and Silk and former presidential candidate Herman Cain.

The group is dedicated to nurturing activists, registering new voters and firing up the faithful. Outreach events and voter contact trainings have already been held in North Carolina, Pennsylvania and Virginia, reps for the organization told The Post.

There is also Trump’s eyebrow-raising friendship with superstar musician Kanye West.

And it all may be having an effect. New data from Harvard CAPS/Harris Poll found Trump’s job approval rating now at 22% with Zogby Analytics finding the same. The numbers are up considerably since a Quinnipiac poll found only 2% of black voters approved of Trump’s job performance in 2017.

“The Trump campaign can encourage black voters by doing policies and programs and reaching out to them on mediums that they read and listen to,” Bruce Eberle, a GOP political consultant and co-author of the new book “COMING HOME: How Black American Will Re-Elect Trump,” told The Post, chalking up the party’s decades-long unpopularity among blacks to communications failure.

“The black church is the most powerful thing in the black community and on cultural issues black voters are more conservative than white voters. Every poll shows that,” he said.

Still the work won’t be easy. In 2016, President Trump received just 8% of the vote from black voters. The campaign was dogged by accusations of racism. During President Obama’s time in office, Trump was the most prominent backer of the “birther” movement, which falsely claimed the president was born in Kenya. In 1989 Trump publicly called for New York to resume capital punishment after five black and Latino men were convicted of raping a jogger in Central Park (the convictions were overturned in 2002.)

Nevertheless, Eberle predicted Trump could run up his numbers nationally among black voters to as high as 17%, with even greater margins in the swing states. “Michigan, Wisconsin, North Carolina, Florida, Virginia. The black voters there, if you reach out to them, you can win 25% of the vote,” he said.

The 2020 outreach effort is already well underway.

Trump’s Super Bowl ad was dedicated entirely to criminal justice reform and the president’s decision to commute the sentence of Alice Marie Johnson — a black woman who spent 21 years behind bars for her non-violent supporting role in a cocaine trafficking ring. “I want to thank President Donald John Trump,” a tearful Johnson says, as her friends cheer her.

At his State of the Union address on Tuesday, Trump repeatedly singled out black audience members for praise, including a 100-year-old former Tuskegee Airman, an Army vet recovering from drug addiction and a young girl who was granted a scholarship to escape her failing school.

“Warning to Democrats: what [Trump] was saying to African Americans can be effective,” political commentator Van Jones told CNN.

“We’ve got to wake up, folks. There’s a whole bubble thing that goes on,” Jones, who is black, continued. “I think what you’re going to see him do: ‘You may not like my rhetoric, but look at my results and my record for black people.’ If he narrow casts that, it’s going to be effective.”
