TRENTON -- Already trailing badly in the polls, Republican New Jersey governor candidate Kim Guadagno has been hit with another devastating 1-2 punch: She's lost the confidence of a pair of deep-pocketed GOP groups that spend big on governor's races, NJ Advance Media has learned.

The Republican National Committee, which is controlled by President Donald Trump, views the lieutenant governor as someone who hasn't been loyal to the president and officials there see her race as a losing cause, according to two sources familiar with the RNC's plans. The sources requested anonymity because they were not authorized to speak publicly.

The Republican Governors Association, a nationwide group formed with the sole purpose of electing GOP governors, has invested minimally in New Jersey and currently has no plans to change course, sources say.

The other hit for Guadagno comes right here in New Jersey, where Gov. Chris Christie's top fundraisers privately say they are sitting out the race because, in part, she's been deemed disloyal to the governor after criticizing him on several issues, including his stay at the governor's beach house during the state shutdown.

Taken together, the withdrawals could cost Guadagno millions of dollars as she heads into the crucial weeks of her campaign against wealthy Democrat Phil Murphy, who spent $21.7 million during his primary campaign.

Facing new urgency in her search for financial backing, Guadagno will travel next week to Aspen, Colo. to seek to support from Republican donors, fundraisers and her fellow GOP governors at the Republican Governors Association summer meeting. The RGA spent $9 million during Christie's two campaigns.

An insider within the RNC's top leadership -- who declined to speak for attribution because such appointees serve at the pleasure of the president -- said the lieutenant governor's dire national fundraising situation stems as much from her double digit lag in recent polls as her public criticism of both the president and the governor.

"[The president] is unhappy with anyone who neglected him in his hour of need," said the RNC insider, referring to Guadagno's public disavowal of Trump after a 2005 video of Trump surfaced last October showing him making crude, sexually aggressive statements.

After the Access Hollywood video surfaced, Guadagno took to Twitter to say she would no longer support Trump.

"Christie was not as stalwart as some people in the party, but at least he didn't go against him the way she did," said the RNC insider.

Guadagno's rebuff of Trump received national attention because Christie was at that time transition planning chief for Trump.

The lieutenant governor has declined to comment about the RNC's lack of support or her struggles with fundraising in-state.

A spokesman for her campaign, Ricky Diaz, said: "We're building our team of individuals who are working hard to raise money for Kim Guadagno's positive message of property tax relief for New Jersey."

However, former Gov. Christie Whitman said Guadagno had spoken openly of the RNC situation to her recently.

"She went down there, and the (Republican National) Committee was reluctant to back the campaign in the way one would have expected. The implication was, 'Well you were not a Trump supporter in the primary, and so don't expect much money,'" Whitman said.

Diaz disputes Whitman's recollection of the conversation. RNC deputy communications director Ryan Mahoney did not return a call for comment.

Whitman said because of the RNC's reaction, "the Republican Governors Association becomes more important to her."

A spokesman for the RGA, Jon Thompson, didn't respond to an inquiry about the group's plans for Guadagno's campaign .

But multiple sources confirmed the spending to date has been "minimal" and there are no plans for that to change. The RGA rarely spends big on candidates so far down in the polls, and is concentrating resources in the tight Virginia race, the sources said.

Christie, a former chairman of the RGA, is also expected to attend next week's Aspen conference, according to a source with knowledge of his plans.

If both Christie and Guadagno are out of state at the same time, Senate President Stephen Sweeney, a Democrat, would become acting governor.

Diaz said Guadagno is "planning on going and it's known for a while that's she going."

Both Whitman and former Gov. Tom Kean say they have counseled Guadagno to attend the RGA meeting in Aspen to secure fundraising, even if it means handing the reins to a Democrat while she's away.

"It's important to her getting her ideas and herself known," said Kean, noting that he was 30 points behind in the polls in July 1981, but went on to win.

Both Guadagno and Murphy are participating in New Jersey's matching funds program under which candidates are allowed to receive up to $9.3 million in public money and limiting to spend $13.8 million.

Support from national groups is crucial because they provide extra help.

The RGA has proven decisive in recent elections: In 2014 it poured $11.2 million into Massachusetts Gov. Charlie Baker's campaign, outspending Democratic groups by more than $3 million. Baker won by less than 2 points.

Back in New Jersey, Guadagno has lost some of Christie's top fundraisers over her repeated jabs at the governor in campaign press releases, according to the sources.

The latest came after the governor was photographed by NJ Advance Media sitting on the beach outside the governor's residence at Island Beach State Park, which Christie had closed to the public during the state shutdown.

Guadagno took to Facebook to excoriate him. She later called for the sale of the governor's beach house.

The governor on Monday said he did not hold a grudge against Guadagno over her comments.

"I don't have any bad feelings about that...I'm a big boy," he said during a press conference in Gladstone. "If you think a couple of criticisms is going to make me weep, I am glad you're not in this business."

Still, Jon F. Hanson, Christie's finance co-chairman during his 2016 presidential bid and both of his campaigns for the governor, confirmed he won't be fundraising for Guadagno.

"I haven't been asked and I haven't volunteered," said Hanson, who said there was "no particular reason" why he wasn't fundraising for the lieutenant governor.

"After a while, you get tired of calling your friends and asking them for money," Hanson said.

Others say Guadagno's campaign has been unfocused when it comes to recruiting prominent Christie donors.

Joseph Grano, a former chairman of Union Bank of Switzerland, said he raised over $100,000 for Christie's reelection in 2013 hosting a fundraiser at his New Jersey home.

However, Grano said he had had yet to be contacted by the Guadagno campaign, even after honoring the lieutenant governor at a November 2016 gala Grano helped to back.

By contrast, a friend of Murphy's has reached out him to set up a lunch with the Democratic nominee.

"I don't know why," Grano said about not hearing from Guadagno's campaign. "But I'm having lunch with Phil Murphy in August."
