CONCORD, N.H. -- The state attorney general is warning voters about a scam that may be an attempt to unfairly influence the outcome of the primary.

Attorney General Peter Heed said someone has been calling voters who are unaffiliated with a party and telling them that they can't vote in the primary -- which is untrue.

Heed said his office has received complaints from town and city clerks as well as undeclared voters who said they are being told they cannot vote.

A voter who is registered to vote in New Hampshire but has not declared a party affiliation may vote in the presidential primary and choose the ballot of either party at the polling place. People who are eligible to vote but are not yet registered may register to vote at the polls on primary day.

Heed urged anyone who receives such a call to contact his office at (866)-VOTER03.
