For residents of the District of Columbia, it’s not exactly a secret that Karl Racine is a very active and ambitious D.C. attorney general—practically every week (and sometimes more than that) he’s filing suits against slumlords, seeking damages for victims of wage theft, opening up investigations into clergy sex abuse, suing Facebook, or going after President Trump.

For years, there has been speculation that all this action is leading somewhere: he’s been considered a potential candidate for D.C. mayor, popular enough that he could mount a serious challenge against incumbent mayor Muriel Bowser. But in 2018, he opted not to challenge Bowser and instead won the most votes of any citywide politician on the ballot when he ran for reelection as D.C. attorney general last November.

His consistent involvement in national lawsuits, and in actions against Trump, have led some to believe he’s gunning for a bigger title: Attorney General of the United States under a Democratic president in 2020. In a Politico profile over the weekend from Dream City co-author Harry Jaffe, Racine didn’t deny it:

Is his heart interested in moving up to serve in federal office? … Would he consider serving as Kamala Harris’ attorney general?

“Of course I would,” he said.

This is the clearest Racine has been publicly about his national ambitions, though local politicos have long been speculating about what might be in his head. “If he continues to make big national headlines, he will be on the shortlist for US Attorney General by a number of the 2020 Democratic presidential candidates,” Josh Brown, political consultant with DP Strategies, told the DC Line in December.

“Don’t expect Racine to find a horse to ride in the upcoming Democratic presidential primary; he’s likely to play it safe and not risk jumping on board early and backing a potential loser. But do expect to see him on the campaign trail stumping for the eventual winner. And then, if a Democrat occupies the Oval Office, I think Racine will be in a good position for a big-time job in the new administration,” consultant Chuck Thies wrote to the DC Line.

Since Racine became the District’s first attorney general in 2014, he’s been busy not just building his own profile, but strengthening the network of Democratic attorneys general across the country, the Democratic Attorneys General Association. As a co-chair of DAGA, he helped turn it from an under-funded, weak organization into one that could compete with Republicans’ much stronger and more active counterpart. As the Politico profile notes, his intervention has propelled several Democratic attorneys general to victory in competitive state elections:

Under Racine, DAGA has become a nimble and well-funded political strike force in Washington—one that in 2018, raised and spent record-breaking sums of money, embarked on a “digital doorknock” outreach campaign that contacted 12 million voters in more than a dozen targeted states via peer-to-peer text messages and played a major role in flipping AG seats in Nevada, Michigan, Wisconsin, and Colorado.

And who can forget Racine’s emoluments lawsuit against Trump, perhaps the clearest indication that he intends to make a national name for himself? Racine and Maryland Attorney General Brian Frosh are suing Trump for allegedly violating the Constitution’s anti-corruption clause in failing to divest from his business interests. So far, Racine and Frosh’s attempts to move the suit forward in court have been successful.

There’s still one last hurdle to jump for Racine in his national ambitions, however. A Democrat has to win the presidency next year. Racine has his preferences, according to Politico:

“I love Kamala Harris,” Racine said. Her husband, Douglas Emhoff, a Los Angeles-based attorney, was a former law partner of Racine’s at Venable, and the two men are close friends. “The opportunity to help someone like Kamala is intriguing,” Racine added.
