2020 Democrats Want to Build a Movement, Not a Traditional Campaign

But some have warned that the embracing of activists could be more about optics than a shift in political power, and that the bulk of decision making will still reside with the political strategy firms that have long been influential in electoral politics. Ms. Harris’s campaign, for example, has deep ties to big political names such as the longtime California consultant Averell (Ace) Smith, the Democratic strategist who has helped her orchestrate several campaigns in advance of her presidential run.

“The proof will be in the pudding,” said Jess Morales Rocketto, the political director of the National Domestic Workers Alliance and a former staff member on Hillary Clinton’s 2016 campaign. “Like who’s getting to decide the budgets, who’s getting to decide where the candidate goes, who’s getting to decide the targeting? Is that the people of color that they hired?”

Ms. Morales Rocketto urged the campaigns to see employees from non-Washington backgrounds as more than just an attempt to “check boxes.” She said one current presidential campaign explicitly told her recently that they were calling her because they needed a “senior Latina with movement credibility.”

“It would be a damn shame if all they did was catch up to the optics,” she added.

Heather McGhee, the former president of the progressive advocacy group Demos, who has not signed onto a 2020 campaign, said she has been contacted personally by Ms. Harris and Senator Cory Booker of New Jersey — though she remains a close ally of Ms. Warren. Her counsel was particularly valued after Demos’s political arm published a much-lauded 2018 paper on how candidates should fuse analysis of race and class, a key focus of the progressive message.

“To see the soul of the new Democratic Party, you can look to the candidate’s advisers and ask whether they came from activism or professional consultant class,” Ms. McGhee said, implying that more now come from grass-roots backgrounds and can inject the party with new ideas.

One such idea was on display when Ms. Harris held a recent campaign rally in Nevada. During the event, aides passed out headsets to Spanish-speaking residents so that the candidate’s words could be translated in real-time, a move widely praised as an effective way to reach new voters in the immigrant-rich West.

It came from Ms. Butler, who said it was a “no-brainer” from her time in union organizing.
