Fringe of competitiveness. The only New England state to vote for a Republican nominee after 1988 suggests a solid Democratic firewall.
NH is quite similar to Arkansas. Being the only independent state in a solid D/R region, it just adjusted to its environment. It has always been a question of time only.
That's a good comparison. But New Hampshire isn't shy about voting for Republicans, unlike Arkansas with Democrats.
Then again, maybe Arkansas will be more receptive to Democrats under a Republican presidency.
