Is Maine trending GOP?

[MASHED POTATOES. VOTE!]

Maine, like New Hampshire, have a large numer of independents frequently switching sides. The two are still Democratic-leaning, although not as solid Blue as other New England states.

It was a low turnout election, mainly for Democrats.  Presidential elections are not.

That's quite true for New Hampshire as well. Recently midterms are good for Republicans while presidential election years for Democrats.
