Bernie Sanders defined Wall Street’s business model as a “fraud” ripe for revolution. Hillary Clinton said the way to untangle a rigged economy is to work within the system.

The final debate before next Tuesday’s New Hampshire primary set the clearest battle lines so far in the contest for the Democratic nomination. The two candidates both cast corporate America as the villain, but they offered drastically different views about how to impose change.

Their face-off at a debate Thursday night was charged with all of the anger, exasperation, gender conflict and anti- establishment warfare that’s been under the surface for months while they were publicly insisting they would stick to campaigning on ideas rather than personal attacks.

Clinton has been grappling with how to deal with the repeated questions from Sanders and others about her ties to Wall Street, and she tried yet another approach in the debate at the University of New Hampshire in Durham.

Explaining Record

She acknowledged that the answer she gave about her paid speeches before big banks during a Wednesday town hall — that she took hundreds of thousands of dollars from Goldman Sachs because they’d offered it — may not have served her well.

"I think I may not have done the job I should in explaining my record," she said.

It seemed unlikely that her latest answers would put the issue to rest, in a year when seething voter anger of Wall Street has propelled Sanders to a 20-point lead in New Hampshire.

It isn’t only Sanders who’s been raising the issue.

In a question submitted by a New Hampshire Union Leader reader, Clinton was asked if she would release transcripts of the paid speeches she’s made. Clinton declined to say yes or no. “I will look into it,” she said. “I don’t know the status.” Some of her contracts for paid speeches included confidentiality agreements that would complicate their release.

‘Artful Smear’

The tone turned as Sanders once again questioned whether Clinton was truly a progressive and called her part of the establishment for raising money from Wall Street, drug companies “and other special interests.”

Clinton accused Sanders of engaging in a “very artful smear” against her by suggesting, but never directly saying, that she was influenced by millions of dollars in campaign contributions and speaking fees she took from Wall Street and other industries.

“Time and time again, by innuendo, there is this attack that he is putting forth, which really comes down to, you know, anybody who ever took donations or speaking fees from any interest group has to be bought,” Clinton said. “Enough is enough. If you’ve got something to say, say it directly.”

With a flash of anger, Sanders said, “Let’s talk about issues.” He began listing ways in which corporate interests have influenced federal laws on the financial sector, drug prices and more, but not directly linking those claims to any actions by Clinton.
