Huh, I guess that the reason that I don't usually hear bad things about the FSP is because me and mine tend to agree with them more than with folks like you. Let me try to explain what I mean.
No, that's not unfair. That's people exhibiting their perfectly reasonable right to move freely between states as they so choose. As far as I'm concerned, a libertarian moving to New Hampshire because there is a large libertarian population just seems logical.
I reckon that the masses of folks who moved up here from Massachusetts changed the New Hampshire political spectrum in a big way. I think that they're a large part of the reason why NH turned blue. That seems more unfair to the people who were already here. (Disclaimer: I'm not a Republican; it's ok with me that the state isn't red anymore.)
Lawmaking bodies, whether at a federal or state level, are built to limit the laws which are passed to those which would actually be beneficial to a large enough part of the population. If the Senate, or the House, or the Governor (veto power), or the Supreme Court (judicial review) doesn't agree with a proposed regulation, they each get their respective chances to stop that law. Congress shouldn't be judged by the number of laws they make; they should be judged by the number of good laws that they make, and the number of bad laws that they turn down. I like Congress better, on both a state level and on a federal level, when there's enough conflict in Congress to keep the bad laws down.
Of course, the "birther" thing is stupid to get tied up over, though.
Why do you think that NH needs more revenue? I think the "pledge" is dumb, but I'd be against a poposed income or sales tax right now. All that money that the government needs is already there, it's just being misappropriated.
Most of the people up north that I know wouldn't like you speaking for them. There are more Republicans and libertarians (per capita) in that part of the state than any other - they're for decentralizing as much as anybody. Besides, a town or a region can still rally together against something which affects them all, like the Northern Pass. That's basically what happened anyways - there was nowhere else in the state which had such strong resistance to the Northern Pass as up north.
Your last point is totally fair. Like I said, I've heard that some of the members are nutty. But I guess you feel like that's representative of the whole group, and I don't. As far as I'm concerned, the FSPers came here not just because it's a low-population state where they might find themselves a voice, but because it's a state that already had ideals similar to theirs.
