Not going to happen, Republicans will win at least one county in ME - and I'm definitely not buying this idea that it only trended R because "Trump was a good fit for the district". Poliquin, LePage and Collins all did extremely well there as well.
Collins is definitely an outlier, but regarding the other politicians you're right.
Wasn't there a SSM ballot measure some time ago that the Mainers approved?
How well (or should I say: badly) was it accepted in the 2nd district?
The county results for the SSM referendum were almost exactly the same as the 2016 election results, with Trump's '16 counties voting against it and Clinton's '16 counties voting for it.
