CONCORD, N.H. -- Hot races and unseasonably warm temperatures helped produce record voter turnout in Tuesday's New Hampshire presidential primary.

With ballots from all but one small town reporting, an Associated Press count showed 526,671 residents voted in the Democratic and Republican primaries, breaking the previous record for a presidential primary of 396,385 in 2000.

With only the town of Windsor yet to report, there were 287,821 Democratic ballots cast and 238,850 Republican ones.

The secretary of state's office was tabulating official numbers Wednesday, but didn't expect them to be available until late afternoon.

"We had 21 candidates on both the Republican and Democratic ballots and those candidates really represented a broad range of ideas and political viewpoints and there really was somebody on the ballot for everybody in this state to take interest in and cast a vote for," said Deputy Secretary of State David Scanlan.

"Certainly, the weather didn't hurt either," he said.

Less than a week after candidates and their supporters were bundled up for temperatures that barely got above zero during the day, they were out in sweaters for primary day, with a high in southern New Hampshire of 67 degrees.

"It was a spring day in early January, which was really fortunate," Scanlan said.
