Raymond Gruender is currently on Appeals-8. A Bush 43 appointee. St. Louis native, WU Law grad. He was the 1994 Republican nominee sacrificial lamb for Bob McCulloch in the race for St. Louis County Circuit Attorney, among other things.
I don’t know that much about him, he doesn’t seems to have distinguished himself in either the good or bad directions in my mind, so I don’t really know what he would do on SCOTUS.
