Democrats, who account for 25.6 percent of registered voters, are the group that changed the most with the influx of new residents, said Andrew E. Smith, a political scientist and director of the University of New Hampshire Survey Center. In contrast to the blue-collar union members whose predominantly Roman Catholic background made them conservative on some social issues, he said, the new New Hampshire Democrat is a "Volvo Democrat," well off and socially liberal. Twenty years ago, about a quarter of Democratic primary voters here labeled themselves liberal, Mr. Smith said; in 2000, more than half did.
