Donald Trump leads Nikki Haley by 10 POINTS in New Hampshire, according to Daily Mail poll on eve of Republican primary

Former President Donald Trump is on his way to victory in New Hampshire’s Republican primary, according to an exclusive poll for the Daily Mail, with a double-digit lead over his main challenger Nikki Haley.

After a big win in Iowa last week, a big win in Tuesday’s primaries could turn the rest of the nominating race into a coronation.

Our eve of primaries show that 51 percent of voters support Trump, while former South Carolina Governor Nikki Haley is at 41 percent.

These numbers could even be an overestimate of Haley’s score from Tuesday. Her supporters are only half as enthusiastic as those who plan to vote for Trump.

And the poll of 651 Republican primary voters in New Hampshire underlines how far Florida Governor Ron DeSantis had fallen before dropping out on Sunday.

JL Partners surveyed 651 registered Republicans and unreported voters in New Hampshire from January 17 to 21. The results have a margin of error of plus/minus 3.9 percentage points

Haley's campaign hopes her large lead among undeclared voters will help her win.  That means they need a large turnout on Tuesday to get less committed voters to the polls

He had only five percent support. The same poll from July last year put him at 33 percent.

James Johnson, co-founder of JL Partners who conducted the poll, said New Hampshire was the best state for Haley in terms of the demographic groups that tend to support her.

“If she can’t win here, she has no chance of winning overall and is headed for a crushing defeat in South Carolina,” he said, referring to the next nominated state.

“If Trump wins on Tuesday, even by single digits, the Trump train will have left the station — and Nikki Haley will be on the platform.”

Haley’s campaign had been betting on a big showing in New Hampshire, but expectations began to lower in the past week.

The state’s “semi-open” primaries allow “undeclared” voters to participate in whatever primaries they want.

And a slew of campaign groups have been working to convince Democratic and independent voters to back Haley in the Republican primaries as the best way to stop Trump.

The poll results show Haley easily beating Trump among undeclared voters, but Trump’s hold on the Republican base more than makes up for that.

So while Haley carries 59 percent of undeclared voters, compared to Trump’s 34 percent, he carries 62 percent of Republicans, while she can only manage 30 percent.

But Haley's problem is that Trump supporters are much more enthusiastic, according to our poll.  Registered Republicans are slightly more enthusiastic than blacks

Ron DeSantis announced his decision to retire on Sunday. That makes the contest a straight fight between former South Carolina Governor Nikki Haley and former President Donald Trump

And they also show a huge gap in enthusiasm between the two.

So while 82 percent of Trump’s supporters say they are “very excited” to vote for him, only 44 percent of Haley’s supporters say the same about her.

Johnson said the problem for Haley was that she was dependent on the support of undeclared voters.

“Our modeling — based on a field survey of New Hampshire voters — suggests we’ll see more Republicans turn out that day, by 62 percent to 38 percent,” he said.

“It’s what pushes Trump to the lead.”

New Hampshire has hosted the nation's first primary since 1920.  In the last seven competitive Republican primaries, five of the winners won the party's nomination.

In other words, Haley is the independents’ choice in a Republican primary.

Her campaign is now focused on increasing the number of undeclared voters participating on Tuesday.

Campaign manager Betsy Ankeny told reporters on Saturday: “If you don’t have a competitive Democratic primary in this cycle, I think you’re going to see more of those people voting in the Republican primaries.

“And we’ve been focused on them from the beginning, in terms of the universities we’re talking to… we’re not just talking to Republicans, we’re talking to Blacks.”

Haley has stepped up her attacks on Trump in the final days of her campaign. She has questioned his mental fitness for the job and sought to draw contrasts between herself and a president whose tenure was marked by turmoil.

“Chaos follows him,” she told CBS on Sunday. “He’s just not at the same level he was in 2016.”
