Even a broken clock is right twice a day so The Clown Prince made the right move to put the experienced and capable Marc Garneau in charge of the cabinet committee concerning Canada-US relations.

Of course Trudeau should have given Garneau a more senior cabinet post in November of 2015 and should have promoted him in this shuffle.  But at least The Space Cadet has now overcome his envy and pettiness sufficiently to give The Space Man an important role in addition to Transport.

As a third rate mind, The Boy Blunder prefers to surround himself with other third rate minds, preferably young greenhorns as clueless as himself, and Garneau is a first rate mind with extensive experience and was Junior's leading rival for the leadership.  (Does anyone really believe had their names been reversed that Justin would have beaten out Garneau? )  So Trudeau deliberately underemployed Garneau in 2015 and again now.

Compare how Mulroney put country before ego  in employing his rival Joe Clark.
