The numbers in New Hampshire are looking nice for Carly Fiorina, who has jumped 10 points in one month, according to a new poll.

The former Hewlett-Packard CEO is now is second place with 16 percent of the potential Republican electorate saying they're for the businesswoman, up from 6 percent in September.

Donald Trump, while still the frontrunner, now gets 21 percent of the vote, a dip from the 28 percent he held in September, so says the new NBC News/Wall Street Journal/Marist poll.

Carly Fiorina is now No. 2 in New Hampshire, leapfrogging Ben Carson, Jeb Bush and John Kasich. While Trump is still No. 1, the former Hewlett-Packard CEO has cut into his lead

Donald Trump is still the frontrunner in New Hampshire, but Carly Fiorina's new found popularity is eating into The Donald's lead

Fiorina leapfrogged over Jeb Bush, who saw slight gains in New Hampshire, moving from a share of 8 percent to 11 percent.

She also jumped over Ben Carson, who fell slightly, moving from 11 percent in September to 10 percent in October.

It looks like the only female GOP candidate drenched the momentum of Ohio Gov. John Kasich, who held the second-place spot in September. Kasich's numbers went from 12 percent to 6 percent.

Moving up the ranks like Fiorina was Florida Sen. Marco Rubio, who saw a seven point gain in a month's time. Rubio was polling at 3 percent in September and now has 10 percent, coming behind Trump, Fiorina and Bush in the Granite State.

On the Democratic side of the aisle, Bernie Sanders continues to best Hillary Clinton, though his lead slightly diminished. He was up 49 to 38 percent in September, now he's up 48 to 39 in October.

The poll also shows what could potentially happen if Vice President Joe Biden entered the race.

While Biden's numbers have remained in the teens – today he stands at 18 percent of the New Hampshire vote – he seems to be sucking support slowly away from Clinton and not Sanders.

In Iowa, Carly Fiorina is now in third place, with Donald Trump and then Ben Carson still in the lead. Trump has lost ground in both early contest states, while Fiorina has made gains

In July, Clinton was winning the New Hampshire race with 42 percent. That had slipped 10 points by September to 32 percent. Now she only gets 28 percent support, to Sanders' 42 percent in a mostly three-way race with Biden.

Martin O'Malley, Jim Webb and Lincoln Chafee are polling 2 percent and below, respectively.

In Iowa, the other early contest state, Clinton and Trump continue to be the frontrunners, according to the NBC poll.

On the Republican side, Trump, along with Ben Carson, are ahead of the pack, but both slightly down. Trump has 24 percent of the vote, followed by Carson with 19 percent in October thus far. In September, Trump's lead was at 29 percent to Carson's 22.
