I did see though that thouasnads of libertarians are moving to NH to help build their party but said int he short term they may support Bush if it appears close, which could help too.
NH could be in play for a moderate Democrat, if not Dean.
As Dazzleman pointed out in another thread, the growth of the "exurbs" (suburbs that don't surround urban areas) is a key national demographic trend that favors Democrats for years to come. Fast growing "exurban" areas in southern NH like Nashua and Manchester are attracting young families from cities like New York and Boston. The "downtown" of these areas are their shopping malls, which don't promote traditionally conservative cultural values like the small towns or rural areas that the exurbs are replacing. The traditional independent libertarian NH voter will eventually no longer dominate NH politics.
This phenomenon is true in other northeastern states like NJ and PA as well.
