2:18 p.m.

Ted Cruz says Donald Trump has no choice but to engage in profanity because the billionaire businessman can't defend his record.

Cruz briefly addressed Trump's latest insult Tuesday afternoon as he greeted voters inside Manchester's Red Arrow Diner, a must-stop for candidates in both parties.

"Part of the reason that Donald engages in insults is because he can't discuss the substance. He can't defend his record. For example, a vote for Donald Trump is a vote for Obamacare," Cruz told reporters as he walked into the diner.

Trump has said that's a "lie." Cruz charges that Trump supports universal health care that could lead to health care rationing.

Cruz says, "Donald can't defend that. So instead, his approach is to engage in a profane insult. I'm not going to respond in kind."

A lot has changed for Vermont Sen. Bernie Sanders as he's risen in primary polls — starting with his ablity to take a walk.

All-but-ignored by the media for more than a quarter century in Congress, the Democratic presidential candidate found himself swarmed by dozens of reporters on Tuesday afternoon in Concord when he decided to take a stroll around the state capital.

"If we have a large voter turnout I think we're going to do just fine," he told the press.

After that, questions were met with stony silence.

"What does he like about New Hampshire," shouted one reporter.

No response.

"Does he miss Vermont?" asked another.

Sanders didn't even crack a smile before jumping into a waiting SUV and taking off.

"He needed a little air," said adviser Tad Devine.

1:40 p.m.

It seemed like an automatic voter conversion moment for Sen. Marco Rubio. Instead, it was a snapshot of the quirky independence of New Hampshire voters and the impression Rubio left on one.

Rubio and Derry Republican voter Stephanie Tespas stood outside Gilbert Hood Middle School in Derry, locked in a quiet and serious conversation about cancer.

Tespas told Rubio of her son's genetic condition, the same as her husband who battled and survived cancer. Rubio was nodding, and mentioned his own father's losing battle with lung cancer after a lifetime of smoking.

But when Rubio shook Tespas' hand, told her "thank you," and got into his SUV to leave, she said she remained undecided about who to support as she walked into the school to vote.

Tespas left the school gymnasium without saying who she supported, except that it wasn't Rubio.

"I just don't think he's quite ready," she said. "I wanted him to be more personal. I felt like I was in one of his commercials."

Rubio has been criticized as a repeater of rote talking points. He must finish strong in Tuesday's GOP primary to have a shot at being the establishment Republican party's favorite.

12:43 p.m.

Chris Christie isn't saying whether his campaign will continue after Tuesday's GOP New Hampshire primary.

At a noontime stop at a Derry restaurant, Christie refused to say what place he needs to come in at a minimum to continue his campaign.

"I don't get into that stuff. Next!" he said, calling on the next reporter.

Christie has hung virtually all of his White House hopes on a strong showing in New Hampshire. Other candidates, such as Jeb Bush, have said their campaigns will continue into the next states to vote, South Carolina and Nevada.

___

12:22 p.m.

Jeb Bush is buoyed by some favorable poll numbers and growing crowds at his town halls. He's hammering away at front-runner Donald Trump and saying his own experience as a two-term Florida governor is a better presidential qualification.

Bush, appearing on Fox News Tuesday, says he's determined to knock down Trump because he says "this guy is not a conservative" and he cannot "win by insulting your way to the presidency."

Bush says he's the only candidate offering detailed plans to lift people out of poverty, raise middle class incomes and keep the country safe.

He says "that's what people want," not "the insults and all the divisiveness."

10:42 a.m.

Chris Christie is telling his campaign volunteers to work now, celebrate later.

Visiting his Bedford headquarters, Christie says the Republican contest is far from over, and that the campaign has much work to do to get voters to the polls.

Christie continued to tout his performance in Saturday's debate, during which he came down hard on Florida Sen. Marco Rubio, saying it solidified the central premise of his campaign: that his work and life experience make him the best prepared to take on Hillary Clinton and win the presidency. And he says he's fine with others criticizing his record, because at least he has one.

9:10 a.m.

John Kasich is searching for votes one cup of coffee at a time.

The Ohio governor is jumping behind the counter at the famous Red Arrow diner in Manchester to pour coffee for guests and even deliver a plate of food.

"I don't want to bother you, but I'm going to bother you!" he's joking with voters enjoying their breakfast.

Kasich is spending the day visiting polling places around the state before joining supporters in Concord Tuesday evening.

Kasich's wife Karen is joining him on the trail for the final hours of campaigning before the polls close.

One of Hillary Clinton's morning stops put her face-to-face with Frank Fiorina, the husband of Republican presidential candidate Carly Fiorina.

Clinton and Fiorina greeted each other at a middle school in Derry, New Hampshire that serves as a polling site.

Clinton asked Fiorina, "Isn't it amazing?"

Fiorina joked that he's not crazy about the snow but the people who come to the polls are "amazing."

Clinton added, "Give my best to Carly."

Donald Trump says his campaign is $45 million under budget as he enters the second race of the presidential nomination process.

Speaking to MSNBC's Morning Joe as polls opened in New Hampshire Tuesday, Trump acknowledged that he's polled well in the Granite State but urged people to go out and vote.

Trump also addressed a possible third-party run by former New York City Mayor Michael Bloomberg, calling Bloomberg his friend, but acknowledging some of his shortfalls as mayor with regard to property development.

Trump has maintained a lead in most New Hampshire polls among his Republican contenders leading up to Tuesday's primary.

Ohio Gov. John Kasich is avoiding making predictions as voters head to the polls in the New Hampshire primary, instead, focusing on his economic plans for the country.

Speaking to MSNBC's Morning Joe Tuesday, Kasich said he expects a "strong finish" in the first-in-the-nation primary, but emphasized his wishes to maintain a positive campaign that promotes job creation and economic prosperity for the American people.

In the tiny town of Dixville, which votes at midnight on primary day, Kasich sneaked past Donald Trump, 3-2, among Republicans. Polls are now opening in the rest of the state.

Hillary Clinton is vowing to "keep working until the last vote is cast and counted" as voting in the New Hampshire primary begins.

Clinton is starting her day before 7 a.m. at a Manchester polling location. She shook hands and posed for photographs with a group of volunteers & supporters.

Polls show Clinton trailing Vermont Sen. Bernie Sanders in the nation's first presidential primary. Clinton narrowly defeated Sanders in last week's Iowa caucuses.

Clinton declined to predict the outcome to reporters, saying she's "looking for a great election."

7:00 a.m.

Polls are opening across New Hampshire, though the exact hours vary from place to place.

State law requires polls to be open between 11 a.m. and 7 p.m. Tuesday. Most allow voting between 8 a.m. and 7 p.m., with a handful opening polls as early as 6 a.m. and about 20 remaining open until 8 p.m. And three tiny towns — Hart's Location, Dixville and Millsfield — had permission to open their polls at midnight and close them moments later once everyone had voted.

Independent voters, officially known as "undeclared," make up 44 percent of registered voters. They can vote in either primary, making them a key group on Tuesday.
