ONO LESSON Donald Trump has learned from his first term that personnel is everything. That could explain the blistering pace of nominations for his government in the week since he won re-election. Unfortunately, that same insight could also explain Trump’s choices to be his top lieutenants, including the appointment as attorney general of Matt Gaetz, a cartoonishly divisive congressman from Florida who is despised even by many in his own party. Too many of them appear to have been selected primarily because their personal loyalty to Mr. Trump will not be limited by any scruples.
