Stacey Abrams has yet to make a decision about whether to run for president in 2020. Technically, Joe Biden is not yet officially running either. But allies of the former vice president are already floating Abrams as his potential running mate, leaving Abrams supporters frustrated that the rising star is somehow being relegated to a second-tier spot.

“It says a lot about her leadership and the passion that she has tapped into across the country,” said Kimberly Peeler-Allen, the co-founder of Higher Heights, an organization dedicated to getting black women involved in politics.

But, she added, “it is interesting that before she has even decided what she is doing, he has decided what he wants her to do.”

The New York Times reported Thursday that Biden’s team is considering the odd move of selecting a running mate “well before the nomination is sealed” and that his “close allies” have zeroed in on the former Georgia House minority leader as a potential choice for the 76-year-old ― one way Biden’s camp is considering assuaging fears that he is too old and too white for the job. Biden reportedly told his aides he found Abrams “incredibly impressive” last week after the two had lunch, where they each discussed their future plans, an Abrams aide said. (The aide did not specify whether they discussed the plan to be on a joint ticket.)

Since Abrams came within 55,000 votes of winning the Georgia governor’s race last year ― as the first black woman to be a major party’s gubernatorial nominee ever ― she has emerged as one of the stars of her party. That was clear last month, when Abrams delivered the rebuttal to President Donald Trump’s State of the Union address. And it is still clear now, as New York magazine runs excited headlines like “Stacey Abrams for …. Governor? Senator? Veep? President?!”

For that reason, Democratic strategists and black organizers expressed skepticism about why a rising star like Abrams would want to hitch her wagon to Biden so early, even if he currently leads in national polls. Yvette Simpson, the chief executive of Democracy for America, a progressive political action committee that supported Abrams for governor before she even entered the Georgia race, said Biden seems to have more to gain at this stage.

“I can see the benefit of Joe Biden selecting a Stacey Abrams,” Simpson said. “What I can’t quite figure out at this stage is what the benefit is to Stacey Abrams.”

For Biden’s team, the political upside of successfully enticing Abrams would be clear. Black women have developed into a dominant force in Democratic primary politics, and Abrams might help Biden convince some black voters to pick him in a field that includes Sen. Kamala Harris (D-Calif.) and Sen. Cory Booker (D-N.J.). “Some could say that is the former vice president recognizing where he may need some help on the campaign trail with black women and women in general,” Peeler-Allen said. It could also help Biden respond to criticisms that he’s been on the wrong side of issues like desegregation and abortion over the years.

For Abrams’ part, she could end up with a clear avenue to the presidency if Biden were to win the nomination with her on the ticket. But Peeler-Allen noted that there would also be a considerable risk: Biden could flame out in the primary as he has twice before, leaving Abrams attached to a losing candidate with many fewer options than she has now.

“There are a lot of chess pieces,” Peeler-Allen said.

On Friday evening, Biden spokesman Bill Russo tweeted that the former vice president has “an enormous amount of respect” for Abrams but “these rumors about discussions on a pre-cooked ticket are false, plain and simple.”
