It could, and should, have been a minor news item; the Democratic National Committee announced a “transition team” as new chair Tom Perez consolidated control.

But as Democrats keep finding out, any move inside the party is watched by some supporters of Sen. Bernie Sanders (I-Vt.) for evidence of betrayal. The 29-member transition team was scoured for supporters of Rep. Keith Ellison’s (D-Minn.) bid against Perez — a campaign in which fewer than 440 people voted — and found wanting. The list’s only high-profile supporter of Sanders was Pramila Jayapal, a new member of Congress from Washington.

“Putting one person who supported Bernie Sanders on your list — it’s a slap in the face,” said Cenk Uygur, the host of the progressive web news series The Young Turks, on a Thursday episode. “We gave the most popular politician in the country one vote, what more do you want?”

Earlier in 2017, Uygur launched “Justice Democrats,” a project designed to replace “corporate” incumbents with primary challengers. And TYT’s chief correspondent on the DNC race, Nomiki Konst, is a member of the more diversified “unity commission,” tasked with reforming party rules ahead of the 2020 primaries — a priority of Sanders.

In statements, Perez and Ellison tried to cool off the accusations of bad faith.

“The transition advisory committee is just a start to the broader transition efforts,” said Perez spokeswoman Xochitl Hinojosa. “Over the weeks to come, Tom Perez and DNC leadership will continue meeting with key stakeholders in our big tent party, including progressive leaders, labor and experts in various fields to discuss priorities for the DNC, grassroots organizing, reaching key voters who were left behind this last election, and raising the resources needed to succeed.”

Ellison told the Huffington Post that he was proud to see a few allies on the committee, and on Twitter, he criticized progressives who were prioritizing party purity while President Trump was introducing an austere budget.

The list includes Sally Boynton Brown and Pete Buttigieg, two Perez rivals who made no endorsement after they lost their DNC chair bids; Jehmu Greene, who endorsed Perez after losing her DNC bid; Jennifer Granholm, the former governor of Michigan; and Mark Begich, the former senator from Alaska.

And it’s the Begich role that especially rankles some on the left. As first reported by McClatchy, Begich helped organize a secret summit with centrist and red state Democrats; meeting in Denver, they decided that “security, opportunity, compassion and results” were the values that united Democrats.

That talk clunks with many on the left, who believe that Democratic opposition to Trump is weaker when it doesn’t adopt Sanders’s message and policies. And that attitude clashes with the one behind the transition team, which is heavy on labor organizers and key party interest groups.

But on Friday evening, Sanders campaign veteran Melissa Byrne, who ran for DNC vice chair, said that she had gotten a call that reflected the discussion about who was and wasn’t part of the DNC.

“A few hours ago, I was asked to join the DNC transition working group,” Byrne wrote on Facebook. “I said yes immediately.”

And an updated press release reported that Nebraska Democratic Party chair Jane Kleeb, a Sanders supporter and Ellison supporter, was added to the committee.
