I am not sure I would call NH a LP stronghold, but I would argue that they have done quite a bit with their freedom. Or to be more to the point they have prevented quite a bit from being done with that freedom.
NH has no state income tax, no sales tax, and for the most part local control of property tax collection and distribution. They have the smallest tax burden of any state per $1000 dollars of income, and are 3rd smallest based on population alone. They have the #1 level of per family retail spending, likely because of the above tax situation. Based on economic indications I would say NH is the most free and vibrant state in the union.
As for the question of personal freedom, although no seatbelt or helmet laws are nice, they could use some work but they still may come out ahead of all the other states we are considering. When considering personal freedoms like privacy, property rights, gun laws and the rest, each state seems to have their own individual foibles.
My personal preference leans twords NH. It is much easier to prevent the expansion of government that to force it to contract and NH has managed to keep the size of their government for the most part small.
