Winning 1 EV is not worth it. ME trending republican is so overrated on this forum. The state trended towards Obama in 2012. It's about as safe as Oregon for the Dems, and ME-02 is as likely Dem as Wisconsin.
Well, he could win 4 electoral votes by winning the whole state. That would be difficult, since ME-01 is basically a more Democratic version of New Hampshire. But not impossible. Remember, in 2008 when we had new candidates, we had large unexpected swings in states like IN, NC, and VA. The map could similarly change this year. LePage has shown the path for Republicans to be competitive in Maine, and all Trump has to do is follow it.
No, ME-1 is like California. No way Trump can win there.
It's more like a mini-Boston with some MetroWest and Essex County fishing towns thrown in, but yeah it's safe Dem.
I was just there (coastal Maine); it struck me as being more like a mini-Vermont except a little less resort/hippie-heavy. Much less overtly liberal culture than Vermont, though.
