Bork was a legal positivist, too, at the time he was being considered for the SC. He might have developed more interest in Thomistic natural-law philosophy as he became a Catholic after that. So Gorsuch may be no more of a wild card than Bork would have been--if he hadn't been Star Chambered by the Chappaquiddick River Pilot.
A sincere originalist could be described as someone who insists on making Congress do its job of writing the laws, and unwilling to pull America's chestnuts out of the fire (or throw them into the fire) by legislating from the bench. Gorsuch could simply be that someone.
I frankly can't imagine sharing his comfort level about sodomy and quasi-legal enshrinements of it. But men who are very willful, as he shows signs of being, have been known to carry on for decades, driving people crazy who expected them to rule in favor of their emotions instead of insisting on a text-supported approach that has been their only comfortable position in a contradictory world.
By virtue signaling his disapproval of Trump on his first day on Capitol Hill, Gorsuch indicated that he is more of a player than a thinker, a club man than a library man.
He will be confirmed, he will disappoint, and we will need to have a plan to deal with it.
There are really no good plans, though, if the Court goes 6-3.
That would be the Dyke Bridge that has since disintegrated and Edgartown Harbor prior to South Beach Break.
Very few people could swim that tide unless it was dead low.
