CONCORD, N.H. (AP) — The New Hampshire Democratic Party has lost phone service — on some or all lines — at local campaign offices at 11 locations around the state.

Michael Brunelle, the party's executive director, said two phone and Internet providers haven't pinpointed the problem. Service was affected in Concord, Manchester, Milford, Dover, Hampton, Nashua, Keene, Plymouth, Exeter, Londonderry and Somersworth starting at 1:30 p.m. Monday.

The party also alerted the state attorney general's office as a precaution.

In 2002, a scheme to disrupt Democrats' get-out-the-vote efforts by jamming telephones with hang-up calls resulted in criminal convictions for former state GOP executive director Charles McGee and former political consultant Allen Raymond.
