A Marist/Wall Street Journal/NBC poll out this week, however, showed a very different snapshot, with Clinton leading Sanders among voters who are Democrats by 18 points.
Among independents and new voters likely to take part in the primary, the Monmouth poll shows Sanders with a 58 percent - 34 percent advantage, similar to his 59 percent - 35 percent lead in November.
Fifty-two percent of these voters say they've settled on their choices, up from 35 percent two months ago. Sanders' supporters (55 percent) are a little more decisive than Clinton's (49 percent).

Clinton charged that Sanders’s policy proposals were unrealistic, that the Vermont senator would raise taxes on middle-class families and that he could not be trusted to fight special interests and protect President Obama’s achievements, including his signature health-care law.
On health care, she argued that Sanders’s “Medicare-for-all” plan would jeopardize the Affordable Care Act and effectively turn over health coverage programs to the states, many of them led by Republican governors.

“If that’s the kind of ‘revolution’ he’s talking about, I’m worried, folks,” Clinton said, a reference to Sanders's call for "a political revolution."
Stump speeches by GOP presidential candidates reveal that they're already planning for a race against Hillary Clinton in the general election. (Peter Stevenson/The Washington Post)Clinton’s speech to a few hundred supporters on the campus of Iowa State University was striking in its sharp tone and the breadth of her attacks against Sanders. Her intensified assault came as a new Quinnipiac poll Tuesday showed Sanders overtaking her in Iowa, 49 percent to 44 percent.
Clinton accepted the endorsement here of the Brady Campaign to Prevent Gun Violence and used the occasion to tear into Sanders for his 2005 Senate vote that gave immunity to gun manufacturers. That bill was a major priority for the National Rifle Association.
Clinton mocked Sanders for claiming that he was voting in line with the interests of his rural state with a deep hunting tradition.
“He says, ‘Well, I’m from Vermont,’” Clinton said. “Pat Leahy, the other senator from Vermont, voted against immunity for the gun lobby. So, no, that’s not an explanation.”

Sanders has vowed to break up the big banks, but Clinton asserted here that she has stood up to special interests throughout her career, including on Wall Street. She said she went after derivatives and corporate executive compensation, and that she helped influence the Dodd-Frank financial regulation bill, which passed after she left the Senate to become secretary of state.
“Don't talk to me about standing up to corporate interests and big powers," Clinton said. "I’ve got the scars to show for it, and I’m proud of every single one of them.”

Speaking more broadly about the challenges of the presidency, Clinton said she was the only candidate prepared to do all the duties of the office. She spoke movingly about her role in the White House Situation Room during the Osama bin Laden raid, calling it “one of the most tense days of my life.”
Without mentioning Sanders by name, Clinton implicitly suggested he was naïve to think he would be able to implement his ideas, especially with a Republican-controlled Congress.
During a speech on economic reform, Sen. Bernie Sanders (I-Vt.), who is running for the Democratic nomination for president, drew applause when he said his campaign is about a movement unifying people of many different backgrounds. (Reuters)“This is hard work,” she said. “I wish we could have a Democratic president who could wave a magic wand and say, ‘We shall do this, and we shall do that.’ That ain't the real world we're living in!"
Clinton appeared to relish laying into Sanders. “We’re getting into that period before the caucus that I kind of call the ‘Let’s get real period,’” she said. “Everybody’s been out there, lots of good energy, I love it. I love the spirited debate on our side.”

In recent days, Clinton has been highlighting her perceived electability, something her campaign is trumpeting in a television advertisement airing here. Pointing to her longevity in the public eye, she suggested that she was the only Democratic candidate who could withstand the Republican attacks in a general election.
“You’ve got to know what you stand for, you’ve got to be able to defend it, and you have to withstand the barrage of attacks that will come against our Democratic nominee,” she said. “I am still standing.”
Chelsea Clinton made her way around New Hampshire today in attempt to convince voters that they should support her mother, Hillary Clinton, as the next president.
Bernie Sanders, Clinton's chief rival for the Democratic presidential nomination, is practically tied with Clinton in voter polls. He now leads Clinton by a slim margin in Iowa for the first time.
Until now, Chelsea Clinton has shied away from directly naming Sanders in her speeches. She took a shot at the Vermont senator when asked by a young voter how to best galvanize young Americans, who are excited about Sanders' candidacy.
The youngest Clinton was on the defensive. “I never thought that I would be arguing about the Affordable Care Act or Obamacare in the Democratic primary,” Clinton said at an event in Manchester. “Senator Sanders wants to dismantle Obamacare, dismantle the CHIP program, dismantle Medicare and private insurance.”
She then went on to say that she believes her mother has a “more robust" record on health care than anyone else in the race.
The Clinton campaign has said that Chelsea Clinton will continue stumping for her mother on the campaign trail. She will join her father, former President Bill Clinton, in Iowa for a joint campaign event this weekend.
