Bernie Sanders was finally given the moment he’s surely been waiting for in Saturday night’s Democratic primary debate: he got to call out Hillary Clinton and her ties to Wall Street, to her face.

The stage was set for Sanders when Clinton was asked how she will convince voters she will level the playing field even though she’s accepted donations from Wall Street. She gave her answer: that she has laid out an “aggressive,” “comprehensive,” “tough” plan to reign in the financial industry. Sanders, practically glowing, was then asked to weigh in on her response.

“Not good enough,” he said, almost without pause. The audience erupted into a round of applause. “Let’s not be naïve about it. Why, over her political career, has Wall Street been the major contributor to Hillary Clinton?

“I have never heard a candidate who have received huge amounts of money from oil, from coal, from Wall Street . . . not one candidate [says], ‘Oh, these campaign contributions will not influence me,’” he said. Sanders continued to say the donors “expect to get something. Everyone knows that.” He then went on to detail how his campaign isn’t reliant on those big-bank donations, that he has no super-PAC, that he has 750,000 small campaign donations at $30 a piece. “That’s who I’m indebted to,” he said, of the small-value donors.

Clinton fired back, saying that Sanders “basically used his answer to impugn my intellect.”

“Not only do I have hundreds of thousands of donors, most of them small, I’m very proud that for the first time, a majority of my donors are women. Sixty percent,” she rebutted. After an explanation about her work protecting downtown Manhattan after September 11 and protecting the economy after the terrorist attacks—an aside that even a discerning tweeter quoted by CBS moderator John Dickerson found difficult to connect to Sanders’s point of Wall Street’s influence in her campaign—Clinton circled back to why she will, in fact, be harder on the industry than Sanders would be.

“My proposal is tougher, more effective, and more comprehensive because I go after all of Wall Street, not just the big banks,” she said.

Sanders’s campaign continued to make his point off stage, e-mailing a list of top lifetime donors to Clinton to a group of reporters that pointed to her history of cozy relations with big banks.

There you have it. All of the candidates think they are the toughest on Wall Street. Only some of them are willing to forgo its shiny coins.
