It's a very elastic area - even more so than the other Northern states that flipped. In my
running model of the 2020 election based on elasticity and Trump's approval, it has already flipped back to the Democrats.
It's also a very poor white area: it's basically a Deep South state - in some cases,
even poorer - in terms of median household income among whites. Maine in general is poor (across all races), but among whites in ME-2, it's even worse.
It makes sense that Trump would do very well there compared to 08/12, but it is not by any means lost. I imagine it'll rebound by much more than any of the Rust Belt states if there is any 18/20 wave, and it might even flip before a state like WI does again - certainly before somewhere like OH.
