The Democratic Party, once buttressed by mill workers in eastern and central towns, has expanded its reach all over the state, but particularly in those same southern counties and along the western edge of the state, near Vermont.Suburbs and exurbs that had spotted the countryside now form unbroken furrows across the southern part of the state; the old mills of Manchester and other towns now house tech firms and universities.
