10 questions about the New Hampshire primary, including, 'Can anyone beat Trump?'

And it all comes down to this.

Former President Donald Trump won the Iowa caucuses in a blowout last week, confirming his dominance with conservatives. Candidates have dropped out and endorsed Trump, including Florida Gov. Ron DeSantis, who did so on Sunday.

Almost the entire Republican Party believes Trump will now be the nominee again and is rallying around him, excluding a minority of ex-candidates and his former U.N. ambassador, Nikki Haley.

So New Hampshire, which holds its primary Tuesday, with its moderate voter profile, offers what very likely will be the last, best chance for Haley to show she can beat Trump.

And she might have to win the primary to turn the narrative tide in her favor.

Here's everything you need to know about the New Hampshire primary:

Can anyone beat Trump?

Haley had been gaining ground on Trump in New Hampshire in recent weeks, but Trump continues to lead by double digits in polls — and the most recent ones suggest Haley's momentum may have cooled.

While New Hampshire certainly features a more moderate electorate than Iowa, there may be a ceiling to Haley's potential support. Voters will have their say Tuesday, and New Hampshire has offered surprises before that have turned the tide of presidential elections.

But a Marist poll of New Hampshire voters taken last week is revealing. Two-thirds of Republicans and Republican-leaning independents said Trump should have immunity from criminal prosecution for actions he took while he was president.

The survey underscored, though, Trump's potential general-election problems. The poll found that two-thirds of the broader New Hampshire electorate, including independents and Democrats, felt he should not have immunity.
