I think they have determined that it is a Trump blowout and that the 1 EV is unlikely to matter. In any event, we'll know something is up if Clinton starts campaigning in Portland. Note that Clinton has campaigned and run ads in NE-02, so they must be pretty sanguine about that one.
Portland is not in ME-2....
Yet Trump was campaigning there. 
One thing to keep in mind is that just because a city isn't in a particular CD (or even state) doesn't mean that its entire TV market isn't. Some major ME-02 towns like Lewiston and Auburn are in the Portland TV market. Also, I think the Bangor TV market is so small that at least one of the stations largely simulcasts Portland TV news, instead of producing their own product.
