By not always voting the way little donny dingbat wants him to vote. By voting according to the LAW, the CONSTITUTION, and a little sprinkling of common sense and caring wouldn't hurt. I don't know if he has it in him to pull that off. We will see or you will depending upon how long you live and how long he serves.
William Barr, the little donny dingbat Attorney General, has a harder row to hoe. Will he hoe it or blow it?
