GRAFTON, N.H. (AP) – The state is checking whether Grafton’s voting machines or people tending them made mathematical errors that didn’t add up at this week’s town and school district balloting.

Selectwoman Jennie Joyce said 193 “yeas” and 198 “nays” don’t add up to 369 and she suspects the problem falls between human error and machine malfunction. Once polls closed and the tallies were logged, nobody did the math before calling it a night, she said.

“It occurred to me after I got home that it didnt add up, after I had time to think about some of the numbers,” she said.

The machines, one for town ballots, the other school district ballots, will be checked, said Deputy Attorney General Orville Fitch.

Town Clerk Mary McDow said LHS Associates of Methuen, Mass., which services the machines, told her the problem could lie with dip switches.

The error could change the outcome of votes on a new police cruiser and a compactor for the recycling center.

Secretary of State Bill Gardner said voting malfunction “happens once in a while. Sometimes it explains itself,” adding it is too soon to discuss a re-count.
