Sen. Bernie Sanders spent weeks championing Graham Platner as the progressive answer to Maine's open Senate seat. Then Politico published a report alleging Platner raped his then-girlfriend in 2021, and Sanders reversed course in less than 24 hours, joining a chorus of Democrats calling on the candidate to step aside.
The speed of the reversal did not spare Sanders from the fallout. Instead, it opened a broader reckoning over the Vermont independent's endorsement habits, one that Democrats and Republicans alike are now pressing with unusual force.
As Fox News Digital reported, Sanders has endorsed more than 70 candidates in the 2026 election cycle, 19 at the federal level, plus another 54 in state and local races. That pace far outstrips comparable progressive figures like Sen. Elizabeth Warren and Rep. Ro Khanna. And the list includes a striking number of candidates now mired in controversy, raising pointed questions about whether Sanders or his political operation bothered to vet any of them before lending his name.
The most immediate damage traces back to Orono, Maine. On May 24, Sanders and Platner appeared together at the Collins Center for the Arts on the University of Maine campus as part of Sanders' "Fighting Oligarchy" tour. Sanders told supporters he would "do everything I can to make sure that Graham Platner is the next senator from the state of Maine."
By Monday, Politico had published its bombshell report detailing the sexual assault allegation against Platner. By Tuesday, Sanders had called for Platner to step aside.
The timeline left critics asking an obvious question: what did Sanders know, and when? The senator did not respond to Fox News Digital's requests for comment on his broader endorsement track record.
Platner's conduct in the days surrounding the scandal did nothing to help Sanders' position. At a town hall event in Portland, Maine, on Sunday night, the evening before the Politico report landed, Platner reportedly called Sen. John Fetterman a profanity.
Fetterman, the Pennsylvania Democrat who has increasingly broken with his party's left flank, did not hold back. In an interview with Fox News, he offered a pointed critique of Sanders' judgment:
"So, I don't know why you want to keep pushing these kinds of people. Maybe he should consider sitting a few out and stop pushing these kinds of communists."
That a sitting Democratic senator would publicly urge Sanders to stop endorsing candidates tells you something about the depth of frustration inside the party. Fetterman's willingness to say it on Fox News tells you something else: the political incentives have shifted enough that distancing from Sanders carries less risk than staying quiet.
Sanders, who has all but closed the door on a 2028 presidential bid, seems to have channeled his energy into reshaping the Democratic bench from the outside. The results, measured by the candidates he has elevated, should concern anyone who values basic due diligence in politics.
Platner is the most dramatic case, but he is far from the only one. Consider the candidates Sanders has backed this cycle, as catalogued by Fox News Digital and highlighted by critics on both sides of the aisle.
Adam Hamawy, a Democratic primary winner whom Sanders called one of the party's "bold leaders," has past ties to Sheikh Abdel-Rahman, the convicted terrorist behind the seditious conspiracy linked to the 1993 World Trade Center bombing. Abdel-Rahman died in federal prison in Butner, North Carolina, in 2017. The nature and extent of Hamawy's connection remain unclear, and the candidate's response, if any, was not included in available reporting.
Melat Kiros, a self-described socialist and political newcomer running for Congress in Colorado, defeated a 30-year incumbent in a primary challenge with Sanders' support. She has made assertions that American foreign policy made the 9/11 terror attacks "inevitable." Sanders praised her as someone who would be a "great ally in Congress fighting for a progressive agenda."
That Colorado upset is part of a broader pattern of DSA-backed challengers toppling longtime Democratic incumbents, victories that thrill the progressive base but leave the party exposed in general elections.
Randy Villegas, a congressional candidate in California, faces scrutiny over reports that he voted to approve confidential settlements related to decades-old child sex-abuse cases during his time as a teacher. Sanders urged supporters to "do everything we can to elect new, bold leaders like Randy who will be a champion for working Americans in Congress."
Then there is Cori Bush, the former congresswoman now pursuing a comeback House bid with Sanders' backing. Bush previously paid her husband with campaign cash and was among the most vocal defund-the-police supporters in Congress.
Sanders' endorsement troubles did not start this cycle. In 2018, he endorsed Andrew Gillum for Florida governor. Gillum narrowly lost to Ron DeSantis, and his post-campaign trajectory included a drug-related arrest in Alabama and a highly publicized incident in a Miami Beach hotel room involving a medical emergency and illicit substances. Sanders had told voters Gillum would "work to provide healthcare for all through a Medicaid-for-All program, raise the minimum wage, invest in sustainable energy."
In 2019, Sanders endorsed Cenk Uygur, the founder of the Young Turks and uncle of controversial streamer Hasan Piker. Sanders said Uygur would "serve ordinary people, not powerful special interests" and called him "a voice that we desperately need in Congress." When an online footprint laced with racist material surfaced, Sanders rescinded the endorsement.
Sanders has also backed Squad members Rep. Ilhan Omar and Rep. Rashida Tlaib, both accused of antisemitism and both carrying anti-Israel and defund-the-police records. Tlaib drew fire for calling the prison sentences of accused Antifa cell members, sentenced to decades behind bars for a violent attack on a Texas immigration facility that federal prosecutors described as an act of terrorism, a "travesty and totally unjustified."
The broader Democratic Socialist movement Sanders helped inspire continues to target primaries across the country, and the vetting failures at the top are filtering down.
The criticism is coming from every direction. Political commentator Rachel Bade, a longtime political reporter, posted on X:
"The Graham Platner fiasco was bad, yes. But now, some Dems are tallying up everywhere else Sanders and his orbit bet wrong this cycle, raising questions about their judgment in elevating untested, unvetted candidates with skeletons nobody bothered to check for."
In a separate Substack article, Bade wrote that "all eyes now turn to the August 4 Michigan Senate primary, where Sanders has endorsed progressive Abdul El-Sayed over centrist Rep. Haley Stevens who has Chuck Schumer behind her." El-Sayed, a progressive doctor, has called for defunding the police, abolishing ICE, and universal healthcare. That Michigan race is shaping up as the next test of whether Sanders' endorsement helps or hurts.
Gun-control advocate Shannon Watts added her voice on X, noting Sanders' endorsement of Nate Blouin, a failed Utah House Democratic candidate who lost his primary earlier in 2026. Watts described Blouin as a candidate "who mocked sexual assault" and added: "It's almost like there's a pattern."
The Republican National Committee seized the moment. RNC national press secretary Natalie Baldassarre issued a statement that did not pull punches:
"Whether it's alleged rapist Graham Platner, anti-cop Abdul El-Sayed, or 'trans kid lover' James Talarico, [Bernie Sanders'] clown car of unvetted and untested candidates is showing the American people just how unfit they are for public office."
Baldassarre added: "We will continue to expose these candidates for who they are, radical socialists who will push their extreme ideology and strip every American of their safety, sanity and freedom."
The RNC's framing is partisan, but the underlying facts are not in dispute. Sanders endorsed these candidates. Many of them carry serious baggage. And the senator's office has offered no public accounting of its vetting process, or whether one exists at all.
Nine of Sanders' 19 federal-level endorsees this cycle have never held office. That is not inherently disqualifying, fresh candidates can bring energy and perspective. But when nearly half your slate consists of political newcomers, the burden of vetting rises, not falls.
Sanders has built his brand on challenging the establishment. Fair enough. But challenging the establishment with candidates who carry rape allegations, ties to convicted terrorists, or histories of approving hush-money settlements over child sex abuse is not insurgency. It is recklessness.
As Speaker Johnson has observed, the socialist wing's growing influence in Democratic primaries raises questions about who actually runs the party. Sanders' endorsement spree, and its consequences, may be the clearest answer yet.
The senator did not respond to requests for comment. That silence is its own kind of answer. When you endorse more than 70 candidates and the ones making headlines are the ones facing allegations of sexual assault, ties to terrorism, and records of defending political violence, the problem is not one bad pick. It is a pattern, and patterns do not fix themselves.
Voters deserve candidates who have been checked out before they get propped up. Sanders seems more interested in building an army than in knowing who he is recruiting.
