Senator John McCain's campaign wants the Attorney General Office to investigate claims of push polling.
New Hampshire Public Radio's Dan Gorenstein has more.
A push poll sounds like a political survey phone call but is an effort to plant negative messages about a candidate or issue.
Under New Hampshire law, a push poller must inform the person contacted who the call is being made on behalf of and provide a phone number. According to the Associated Press, that hasn't been provided in certain calls made over the last week.
Allegedly the calls praise McCain and slam Mitt Romney for his Mormon faith and Vietnam draft deferments.
Campaign vice chair Chuck Douglas hand-delivered the complaint.
"We find the whole thing a very bad trend eight weeks or so from the primary."
Douglas, staffers and press then boarded McCain's bus, the Straight Talk Express. They were off to pick up the Arizona Senator from the airport, who's campaigning here for the next few days.
