If the rumors are true and Steve Bannon and Steve Miller are really pulling the strings, then there is just about zero chance we will see a Mormon get a job like SCOTUS. Christian Dominionists hate Mormons the way Shiites hate Sunnis, and there is no way they would allow a SCOTUS pick who is potentially a moderate on immigration.
If chosen, he will likely be a decent pick. He is an originalist, but at he has a better respect for precedent than did Scalia.
