The right response to this crisis is a retooling of the Democratic National Committee to align it more closely with movements for social and economic justice. The party must make the inside/outside connection that will strengthen immediate resistance to the Trump regime, while improving the long-term electoral prospects of Democrats. Keith Ellison, co-chair of the Congressional Progressive Caucus, is prepared to do just that. In an impressive field of contenders for the position of DNC chair—including party leaders that The Nation has often praised, like former labor secretary Tom Perez, as well as energetic newcomers like Pete Buttigieg, the mayor of South Bend, Indiana—it is Ellison who combines the ideals, skills, and movement connections that will revitalize the party.

That’s why The Nation enthusiastically endorses Ellison in the contest to lead a DNC that must repurpose itself in order to derail Trump, while at the same time speaking to young voters who won’t settle for anything less than an aggressively progressive opposition party. The job of DNC chair is to build a party that can win elections on every ballot line and in every state. But in an age when party loyalties are weakening, and when movements matter more to tens of millions of Americans than partisan labels, Ellison is ready to build an activist party. In fact, the high-energy congressman (who says he’ll quit his House seat if he wins the DNC post) is already doing that: calling for mass rallies to oppose Trump’s Muslim ban, taking part in those rallies, and then appearing on the Sunday-morning talk shows to rip discriminatory policies as un-American.

Ellison is recognized as a pioneering political figure—the first Muslim congressman, the first African American to represent Minnesota in Washington—who has boldly opposed wars, defended civil liberties, protested racial injustice, and rallied for “$15 and a union.” His leadership bid has excited activists who have marched with him for labor rights, women’s rights, and criminal-justice reform. It has also inspired blowback from some party insiders, who gripe that Ellison is too outspoken in his support for Middle East peace, too close to Bernie Sanders (though he joined Sanders in ardently backing Hillary Clinton last summer), and too passionate in his belief that the DNC must campaign not just for candidates but for justice.
