Mountain West Research conducted the poll in question, according to the New Hampshire Union Leader. The Idaho-based firm was conducting the survey on behalf of Anzalone Liszt Research, which lists Hodes as a client on its website.

The Hodes camp declined to comment specifically on the poll.

“All of our polls are lawful and conducted for statistical purposes only, not to disseminate messages,” Matt House, a spokesman for Hodes’s Senate campaign, said in a statement. “This is just another partisan stunt from the New Hampshire Republican Party. Rather than spending their time filing frivolous complaints and trying to score cheap political points, John Sununu and the state GOP should focus their energy on refereeing an increasingly nasty and divisive Republican primary.”

Ayotte faces a four-way race for the GOP Senate nomination against businessmen Bill Binnie and Jim Bender and former gubernatorial candidate Ovide Lamontagne. But with the support of Washington Republicans and prominent conservatives like Sarah Palin, Ayotte is expected to be the nominee to face Hodes.
