"Mostly Repub nominations."
Exactly. Of the 12 active judges (Senior Judges do not vote when the circuit meets en banc), only 1 was a Carter nominee and 4 were Clinton nominees, so 7 of the 12 were nominated by either Ford, Reagan, Bush 41 or Bush 43. Remember, judges nominated and confirmed in 1992 were nominated by George H.W. Bush, since Clinton didn't take office until January of 1993.
