ME has had that strange ME 2 that gives R a chance. That's why Collins can still win as well as LePage and why Gov race was close in 2018. Rs can still win in NE, Sununu and Phil Scott.
Sabato has made VT and NH Gov Safe R, Chris Sununu isnt John Sununu and has governed like a moderate
Sununu really hasn't governed like a moderate, especially on voting rights issues. In fact, I'd argue that Sununu era NH has had the second-largest lapse in voting rights since Trump got elected. He also gave the Education Secretary post to a political crony to appease the party base. (Actually, his Chief Justice nominee just got rejected for being a similar political crony!)
Sununu has governed like a bog-standard Republican, really. He's just not offensive enough on key issues for voters to care, so the smiley moderate-types vote for him.
