Thomas is actually very sound.
I would happily leave Clarence Thomas on SCOTUS as an exception but a SCOTUS filled with 45-year olds who are articulate, scholarly, good writers like Scalia, is also a strong temptation. If Thomas is willing to be Chief Justice, that would also work for me as he could introduce the young uns to SCOTUS procedures and lead them. I don’t want ANY of our new justices dying on us but Thomas has certainly earned the right to stay and a promotion. God bless!
