As America slouches toward the midterms, there is some trepidation over what rough beast will be born. A recent poll showed that Democrats have lost ground to the Republicans, while President Donald Trump’s approval rating has clawed up to 41 percent. With a blue wave less of a sure thing, the activities of various political groups have come under the microscope, particularly those that are aiming to shake up Democratic politics and push the party to the left.

Bernie Sanders’s 2016 primary campaign gave rise to a constellation of left-leaning organizations. Combined with his burgeoning media machine, it was a sign that leftists, social democrats, and others were getting serious about winning elections. But veterans of the Sanders campaign have not been able to consistently translate grassroots energy into political success. Meanwhile, the mission of the Sanders Institute, a think tank launched in 2017, remains unclear: Though it achieved recent acclaim for a thorough report on the viability of a federal jobs guarantee, it may be hobbled by the kind of questionable personnel choices that have dogged other lefty groups (the presence of Rep. Tulsi Gabbard, who has voiced support for Narendra Modi and Abdel Fattah el-Sisi, among its “fellows” does not encourage much confidence).

The biggest of those Sanders-inspired groups, Our Revolution, was founded to support candidates who adopt the Sanders platform as their own—and it is facing its own share of problems. On Monday, Politico reported that Our Revolution’s fundraising has declined, that it has “shown no ability to tip a major Democratic election in its favor,” and that it is being roiled by controversies surrounding its president, Nina Turner, who critics say has used Our Revolution as a vehicle for her own political ambitions.

Staffers were particularly incensed by Turner’s recent decision to hire a personal friend and Sanders campaign veteran, Tezlyn Figaro, to work for the organization, despite the fact she has taken some dubious positions in the past:

Board members flagged Figaro’s frequent appearances on Fox News praising Trump. She has said on the network as recently as the end of April that the president’s critics mostly don’t like that he’s shaking up the system. And last year she said immigrants are “coming into the country and getting benefits that Americans do not get,” and getting away with crimes while African-Americans go to prison.

The Politico piece had been live for barely an hour when Figaro started publicly attacking Lucy Flores and Catalina Velasquez on Twitter. Flores is a former state lawmaker in Nevada who stepped down from Our Revolution’s board in April following disagreements about the group’s outreach to Latinos; Velasquez, a founding board member, is an undocumented immigrant. Both are quoted in Politico’s piece. Figaro’s public attacks on Flores and Velasquez are more than troubling, as they occur in a political era marked by White House xenophobia and rising deportations. And all of this reinforces concerns about Turner’s leadership of the great legacy institution of the Sanders campaign.
