Our current political class is so poor that it would take a spectacularly incompetent politician to stand out. Chuck Hagel managed just that with a job application performance that made even dumbest of Democrats cringe.
It used to be a principle of management that A-level bosses hired A-level subordinates. They wanted the best they could get.
B-level bosses hired C-level and D-level subordinates. They were (despite, or because of, raging narcissism) they could not stand a challenge.
Mr. Obama nominated Mr. Hagel. I rest my case.
