Tom Perez elected as new DNC chair

There is one real difference between the two: Ellison has captured the support of the left wing. Ellison backed Sanders early in his primary race against Hillary Clinton, and was one of the first candidates to announce his bid for DNC chair. His election would generate goodwill from Sanders supporters—or, to put it another way, would avoid the enmity that would surely result from a Perez win.

As Jeff Stein points out at Vox, Sanders supporters are likely overstating the power of the DNC chair. But that is all the more reason to throw them a win. If an Ellison victory is a modest, symbolic concession, the upside is that Democrats will signal to progressive and younger voters, who Democrats will be desperate to turn out in 2018 and 2020, that they are on their side. It would be a choice of utmost pragmatism.

But members of the Democratic establishment don’t quite see it that way. The Hill reports, “Perez supporters have expressed concern about handing the party over to the Sanders wing of the party, arguing that Ellison would move the party too far to the left.” And the New York Times suggests that Democratic leaders pushed Perez to run because they viewed Ellison as too close to the Sanders wing.

It appears that the underlying reason some Democrats prefer Perez over Ellison has nothing to do with ideology, but rather his loyalty to the Obama wing. As the head of the DNC, Perez would allow that wing to retain more control, even if Obama-ites are loath to admit it. Sanders has been accused of re-litigating the primary in his criticisms of Perez, but the fact that Perez was pushed to run, while Ellison was quickly and easily unifying the left and center, seems like the move most predicated on primary scars.
