NH is not a blue state. We may elect Democrats federally (Hassan and Pappas are more right leaning than most Dems too), but Republicans rule state government and our laws and governance is very libertarian (no seatbelt laws, no mandatory car insurance, no income tax, no sales tax, very low state spending/minimal welfarism, expansive gun rights, school choice/lots of homeschooling, etc.).

If youre wanting an actually blue state and want to live in the northeast VT, MA, RI, and CT would be more up your alley. If you dont care either way thats also an option, but just be aware Democrats have held government majority in NH for 4 years in the states entire existence.
