Why Trump Supporters Believe He Is Not Corrupt

Cohen’s admission highlights one of the enduring riddles of the Trump era. Trump’s supporters say they care about corruption. During the campaign, they cheered his vow to “drain the swamp” in Washington, D.C. When Morning Consult asked Americans in May 2016 to explain why they disliked Hillary Clinton, the second-most-common answer was that she was “corrupt.” And yet, Trump supporters appear largely unfazed by the mounting evidence that Trump is the least ethical president in modern American history. When asked last month whether they considered Trump corrupt, only 14 percent of Republicans said yes. Even Cohen’s allegation is unlikely to change that.
The answer may lie in how Trump and his supporters define corruption. In a forthcoming book titled How Fascism Works, the Yale philosophy professor Jason Stanley makes an intriguing claim. “Corruption, to the fascist politician,” he suggests, “is really about the corruption of purity rather than of the law. Officially, the fascist politician’s denunciations of corruption sound like a denunciation of political corruption. But such talk is intended to evoke corruption in the sense of the usurpation of the traditional order.”

When Trump instructed Cohen to pay off women with whom he’d had affairs, he may have been violating the law. But he was upholding traditional gender and class hierarchies. Since time immemorial, powerful men have been cheating on their wives and using their power to evade the consequences.
The Iowa murder, by contrast, signifies the inversion—the corruption—of that “traditional order.” Throughout American history, few notions have been as sacrosanct as the belief that white women must be protected from nonwhite men. By allegedly murdering Tibbetts, Rivera did not merely violate the law. He did something more subversive: He violated America’s traditional racial and sexual norms.

For many Republicans, Trump remains uncorrupt—indeed, anticorrupt—because what they fear most isn’t the corruption of American law; it’s the corruption of America’s traditional identity. And in the struggle against that form of corruption—the kind embodied by Cristhian Rivera—Trump isn’t the problem. He’s the solution.
