MERRIMACK, N.H. -- A presidential campaign has been accused of engaging in illegal push-polling practices, using tactics that have left a local nurse feeling the heat from irate voters.

A push poll is a phone survey that asks voters who they support and then tries to change their minds with negative attacks. It's designed to seem like an actual poll, but the questions are slanted against certain candidates.

It's illegal in New Hampshire, but some voters are reporting that they have received such calls that seemed to support Republican candidate Mike Huckabee.

Hospice nurse Trisha Joy has been caught in the crossfire of the tactic. On Friday night, the phone she uses to be on call 24 hours a day suddenly started ringing off the hook with irate voters.

"The women were yelling, 'Don't call my number again! I don't know who you are. Don't call my number again!'" Joy said.

The voters were apparently trying to call back the organization that had called them with the push poll, but they ended up going to Joy's phone.

Voters said that the automated call asked people to choose between Huckabee, Mitt Romney, Rudy Giuliani and John McCain. If the voter didn't pick Huckabee, the other three candidates were criticized on abortion and gay marriage issues.

No one knows for sure who is behind the push-polling, but the Huckabee campaign said it has nothing to do with the calls and asked the attorney general to investigate them.

"This is the worst politics at the worst time of the year," said state Sen. Bob Clegg of the Huckabee campaign. "We believe it's someone who wants to get at Mike Huckabee."

The group claims to be Common Sense Issues and gives a 10-digit phone number. The number given has an area code that doesn't exist, so anyone calling back was bumped to Joy's line.

The calls from voters have been constant, and while News 9 was interviewing Joy, an irate voter called her phone. Joy compiled a list of more than 100 phone numbers from people calling to complain before she gave up trying to track them.

"It's just so frustrating," she said.

Joy called Verizon but said the only fix may be getting a new number. She said she's hesitant to change her number because she doesn't want to risk losing touch with her ailing clients.

Joy has actually been on both sides of the push-polling saga. Monday night, when her home phone rang, it was the automated callers from Common Sense Issues, calling to ask her opinions about the Republican primary race.

The attorney general has a list of the irate callers and is investigating.
