'Dirty Tricks' Operation Behind GOP-Aligned Super PAC With a Progressive-Sounding Name Exposed
The mysterious Lead Left super PAC has been meddling in Democratic congressional primaries across the US.
May 27, 2026
A super political action committee with a progressive-sounding but with Republican financial backers that has been meddling in Democratic primaries was further exposed Wednesday by independent journalist Judd Legum as a clear example of a “dirty tricks operation.”
Legum's new reporting on the funding behind a mysterious super PAC called Lead Left, which recently spent hundreds of thousands of dollars to benefit Maureen Galindo, a failed Democratic candidate for US Congress in Texas who has been broadly condemned for antisemitic rants.
According to Legum, Lead Left is linked to Republican operative Caleb Crosby, treasurer of the House GOP-aligned Congressional Leadership Fund (CLF) super PAC.
"Several pieces of evidence point to Crosby’s involvement," explained Legum. "First, of the roughly 48,500 distinct political committees that have filed with the FEC since 2016, only two others share an address with Lead Left — the Staples at 2241 North Monroe Street in Tallahassee. Both of those committees are connected to the Crosby Ottenhoff Group, the political compliance firm founded by Crosby.
1. Lead Left, a super PAC created on 4/24, purports to stand "against MAGA extremists."
It has spent $3M+ in Democratic primaries.
But it's funders and motivations have been secret.
Until now.
It's a GOP dirty tricks operation.

Legum also documented what he said were "substantial similarities" in messages run against Democratic candidates by both CLF and Lead Left.
"In Nebraska, the American Action Network, the affiliated non-profit of the CLF, sent mail and ran digital ads seeking to damage House Democratic candidate and John Cavanaugh by linking him to Trump," explained Legum. "Before the Democratic primary, Lead Left then ran television advertisements with a nearly identical message."
In addition to spending money to boost Galindo, who lost to Democratic rival Johnny Garcia on Tuesday by more than 20 points, Lead Left this month also spent over $1 million in an attempt to derail the candidacy of retired firefighter Bob Brooks, who last week won the Democratic congressional primary in Pennsylvania's 7th congressional district and will now face off against incumbent Rep. Ryan MacKenzie (R-Pa.).
Elected Democrats, including House Minority Leader Hakeem Jeffries, have accused GOP-backed interests of funding Lead Left, which they say is misleadingly posing as a progressive organization to boost the prospects of fringe candidates and hurt the party's chance of retaking the House in 2026.
We are at a crossroads
This country and this world are at a monumental crossroads. US voters have an opportunity to beat back the forces of fascism and confront the billionaires who are rigging the economy, our media system, and our democracy, making it increasingly impossible for ordinary people to get by. We’re not just talking about the election. We’re talking about what must be done once these fascist elements are vanquished from power. We need a bolder set of solutions than what either major party has so far been willing to offer and a working-class movement ready to fight like hell for it. Trump didn't emerge from nowhere. The conditions that fueled MAGA authoritarianism were created by decades of radical neoliberal economic policies and a corrupt political system dominated by corporate interests. They slashed taxes on the super-rich, promising that the benefits would trickle down. They said giveaways to the corporate titans would make life more affordable for the rest of us. It was all bullshit. And when a bitter, betrayed populace searches for someone to blame, right-wing demagogues have little trouble finding scapegoats. People know when they're being lied to, but you won't hear any of this from the corporate media. Only independent journalism—powered and funded by people who believe in building a better world—can deliver truly trustworthy daily news. If you share our vision, please contribute whatever you can to sustain our work. |
