Manchester, New Hampshire (CNN) – An early proponent of Jon Huntsman is dropping his support over what he calls mismanagement of the candidate's effort in New Hampshire, and will back Newt Gingrich instead.
Richard Brothers, a former state commissioner of employment security who was listed as an alternate convention delegate for Huntsman, said until recently the candidate's national team did not follow a sound strategy for winning New Hampshire's first-in-the-nation primary.
"It seems like they didn't listen to the locals early on, and I think that's the reason that his campaign really doesn't seem to go anywhere," Brothers said. "It seemed like the New Hampshire campaign was being run outside New Hampshire for quite awhile."
Brothers said the campaign deployed Huntsman to "the wrong parts of the state," instead of focusing on areas where the moderate politician might have better prospects. He said he raised his concerns "repeatedly" with the national team to no avail.
Now, he said, Huntsman is campaigning more in the Northern and Western parts of the state. But he called the push "too little too late."
The Huntsman campaign released a statement denying Brothers' allegations.
"Richard Brothers has left the campaign and his accusations are false," said spokesman Michael Levoff. "We wish him the best in his future endeavors."
On Monday, Huntsman's campaign released the list of a statewide leadership team comprising 140 individuals from 90 towns in New Hampshire. The move is meant to emphasize Huntsman's organization in the state, where he has concentrated his presidential efforts since moving his headquarters here in September.
Huntsman has hosted 120 events in the Granite State.
A CNN poll released last week showed the candidate with 8% support in the state.
Brothers' defection to the Gingrich camp was first reported by CNN. He will now advise Newt Gingrich's campaign on veterans' affairs.
Another high-profile Huntsman supporter switched sides Monday. The candidate's former national campaign manager Susie Wiles will join Mitt Romney's election effort, his campaign announced.
Wiles, who parted ways with the Huntsman campaign this summer, will co-chair Romney's Florida advisory council.
