The cryptocurrency industry has a new line of attack against candidates who have voted for consumer protections on digital coins: calling them corrupt.

In at least two Illinois congressional primaries, candidates vying for the progressive vote are being accused by a crypto political action committee of corruption. Fairshake PAC is trying to smear one candidate backed by Sen. Bernie Sanders, I-Vt., as a corporate tool and another candidate who successfully fought a federal indictment as a tax cheat.

The industry has thrown at least $3.3 million into negative attacks on the campaigns in the 2nd and 7th Congressional Districts thus far, according to an analysis from a Chicago political consultant. That spending represents only a fraction of the PAC’s war chest for the remainder of the primary season.

“Ironically, we’re in a very anti-corruption moment, and you know that is true because one of the most corrupt actors in the country is trying to appropriate an anti-corruption argument,” said Jeff Hauser of the Revolving Door Project, a crypto industry critic. “The threat is that the cynical deployment of an anti-corruption politics undermines the potential for success of a genuine anti-corruption politics.”
