NORTH CONWAY, N.H. — Bernie Sanders started the day here by swiping at Donald Trump — but not chief rival Hillary Clinton, who will also campaign in the Granite State today after assailing the Vermont senator yesterday in Iowa as a dreamer whose ideas “will never make it in the real world.”

Sanders’ campaign has fired back, but the progressive firebrand himself has declined to lash out at Clinton in the hours since, mainly focusing on a few policy differences, such as Social Security, and pointing out he doesn’t have a super PAC.

“You turn on the television in New Hampshire, and you’re going to see a lot of ads paid by groups you’ve never heard of,” said Sanders. “Those groups are funded by the millionaires and billionaires of corporate America.”

The latest polls this week show Sanders leading Clinton in New Hampshire, 60-33 percent, and in Iowa, 51-43 percent.

Clinton this morning sent out an e-mail to supporters acknowledging her campaign is in trouble.

“The polls are getting tighter in Iowa and New Hampshire,” Clinton wrote, asking supporters to volunteer. “Our opponent has been outspending us on TV, and there’s a real possibility we could lose those contests if this team doesn’t step up to close the gap.”

Sanders may amp up the rhetoric later today, as he hosts town halls in Concord, Bedford and Hudson, but his sharpest attack this morning was aimed at the Republican front-runner billionaire.

“Unlike Donald Trump and some other Republicans, what we do is bring people together, not scapegoat and engage in bigotry and racism,” said Sanders.

Clinton was endorsed earlier in the week by Planned Parenthood — she is speaking at a NARAL Pro-Choice Massachusetts dinner in Concord tonight — but Sanders has received some of his biggest applause lines in the last two days by calling for protecting abortion rights.

“Nobody will be a stronger defender of women’s rights to choose than Bernie Sanders,” he told the crowd this morning, marking the anniversary of the Supreme Court’s Roe v Wade abortion decision. “Republican family values are about defunding Planned Parenthood. I want to increase funding for Planned Parenthood.”

At the packed gymnasium in North Conway of 685 people, Sanders railed against big corporations, the Koch brothers and other familiar themes.

“Are you ready for a radical idea on a cold morning?” Sanders asked the crowd. “Maybe we should invest in education and jobs for our kids, not jails and incarceration.”

At one point, criticizing the high cost of health insurance, Sanders asked the crowd to shout out their deductibles.

“$6,000,” said one woman.

“$8,000,” said another.

“$12,000,” said one man, as the crowd gasped.

“You lost,” Sanders replied.
