SWANZEY, N.H. (AP) – It turns out a programming error caused a vote-counting machine to throw out hundreds of ballots in the Monadnock Regional School District elections.

L.H.S. Associates of Methuen, Mass., which sells and operates the machines, made a mistake that caused the machine to discard ballots in which residents marked more than one candidate in two races. In each race, voters could choose two of three candidates.

Hand recounts reversed the results in the races and reversed the outcome of a vote on a warrant article.
