"
In Maine they support Trump? That is surprising."
Oh, no, not the majority, except in the Second Congressional District. But most Republicans who voted in Maine did vote for Trump. See the table here. The at-large vote was fairly close.

Those who voted for Collins for lack of a more conservative candidate will be watching to make sure that she votes for confirming Judge Kavanaugh, and most of them are probably smart enough to see through the hysteria broadcast by Democrats about one feminist issue. As far as I know, he only wrote an opinion against immediate taxpayer funding of an abortion for an illegal alien with the likelihood that a sponsor would take care of it soon afterwards.
It appears from a little reading here and there, that many Maine Republicans do value some of their freedoms and lean more towards strict constructionism in regards to the Constitution.
My guess is that many Republicans in Maine will do as many Republicans across the U.S.A. have done. They'll get the most important votes that they want from Collins (the Kavanaugh confirmation being the #1 priority), or...something that the establishment won't want to happen. ;-D
