When Donald Trump became the heavy favorite to win the Republican Party’s presidential nomination, news leaked out of Clinton world that the campaign against him would resemble the 2012 campaign Democrats ran against Mitt Romney. “The emerging approach to defining Trump is an updated iteration of the ‘Bain Strategy’—the Obama 2012 campaign’s devastating attacks on Mitt Romney’s dealings with investment firm Bain Capital,” Democratic operative and campaign aides told Politico. “This time, Democrats would highlight the impact of Trump’s four business bankruptcies—and his opposition to wage hikes at his casinos and residential properties—on the families of his workers.”

That idea was puzzling to some liberals because, for all the superficial similarities between Trump and Romney, they represent very different kinds of oligarchs: Trump, a tribune of the working class, versus Romney, a champion of capitalism and big business. Trump’s everyman-billionaire political identity, taken at face value, is much harder to weaponize than Romney’s was. The fear was that if Democrats set about reprising the 2012 campaign against a self-styled populist, it would fail or backfire. Trump, after all, acknowledges his personal avarice— “I‘ve been greedy, greedy, greedy.” His promise now is to turn that greed outward on behalf of us.

Fortunately, the steady pace of disclosures from the civil case against Trump University—including testimony from Trump employees who say his business-education program scammed the vulnerable out of tens of thousands of dollars a head—provides Democrats a way to repurpose the Romney strategy against a very different kind of foe. The Trump University scam undermines the very notion that a man of Trump’s greed can ever be trusted to advance the interests of others. If exploited properly, it will be Trump’s undoing.

The Democrats can capitalize on lessons they learned from 2012. Early in that campaign, they ran up against a problem they hadn’t planned for. When they pressed voters in focus groups for their views on Romney’s economic platform, it didn’t rate as negatively as they expected, because voters literally couldn’t believe the premise of the questions: Why would anyone who wanted to be president propose privatizing Medicare and giving rich people enormous tax cuts? For a scary number of voters, it just didn’t compute.

Trump University will dramatize the truth about Trump for those voters in the same way Bain Capital dramatized Romney’s stone-heartedness.

The sustained attack on Romney’s private equity career and his capital worship—the ads featuring people whose lives were ruined by the “creative destruction” Bain Capital rained down on their places of employment, and quoting Romney telling a voter, “Corporations are people, my friend”—allowed Democrats to dramatize the story they were trying to tell about Romney’s political agenda.
