Fireworks fly as Clinton, Sanders square off

DURHAM, N.H. -- Fireworks flying in their first one-on-one debate, Hillary Clinton accused Bernie Sanders on Thursday night of subjecting her to an "artful smear," while Sanders suggested the former secretary of state was a captive of America's political establishment.

The two Democrats embraced a markedly more contentious tone than when they last debated before the year's presidential voting began in Iowa, signaling how the race for the nomination has tightened five days ahead of the first-in-the-nation primary Tuesday in New Hampshire.

The two argued over ideas, tactics and who has the liberal credentials to deliver on an agenda of better access to health care, more affordable college, fighting income inequality and more.

Clinton was the main aggressor, saying Sanders never could achieve his ambitious and costly proposals. She went after the Vermont senator for his efforts to cast her as beholden to Wall Street interests because of the campaign donations and speaking fees she's accepted from the financial sector.

"It's time to end the very artful smear that you and your campaign have been carrying out," she said.

Sanders, for his part, suggested Clinton's loyalties were colored by a reliance on big corporate donors.

"Secretary Clinton does represent the establishment," he said. "I represent -- I hope -- ordinary Americans."

Clinton may say the right things, he suggested, but "one of the things we should do is not only talk the talk, but walk the walk."

"I am very proud to be the only candidate up here who does not have super PAC, who's not raising huge sums from Wall Street and special interests," he said.

Where Clinton aimed considerable criticism at Sanders, the Vermont senator focused much of his fire on what he said is a political system rigged against ordinary Americans.

He said when a "kid gets caught with marijuana, that kid has a police record." But when "a Wall Street executive destroys the economy" and pays a $5 billion settlement, he has no criminal record.

"That is what power is about; that is what corruption is about," he said.

Clinton, unwilling to cede the issue to Sanders, insisted her regulatory policies would be tougher on Wall Street than his.

"I've got their number," she said, "the Wall Street guys."

Asked whether she would release transcripts of her paid speeches to Wall Street interests and others, Clinton was noncommittal, saying, "I'll look into it." She had struggled a day earlier to explain why she accepted $675,000 for three speeches from Goldman Sachs.

Clinton called Sanders' sweeping proposals on health care and education "just not achievable," while Sanders countered Clinton was willing to settle for less than Americans deserve.

The race for the Democratic nomination, once seen as a sure thing for Clinton, intensified this week after Sanders held the former secretary of state to a whisper-thin margin of victory in Iowa's leadoff caucuses.

The tone of their back-and-forth has become increasingly sharp, and the candidates agreed to add four more debates to the primary-season schedule, including Thursday's faceoff in Durham.

In fresh evidence of the tightening race, Clinton reported her campaign had raised $15 million in January -- $5 million less than Sanders and the first time she's been outraised by her opponent.

Her finance director called the numbers "a very loud wake-up call."

Sanders has a big lead in New Hampshire polls, but he was eager to lower expectations for his finish there, casting himself as an underdog.
