Beyond all, 2015 was a repudiation of Harper.  Geez, one can't even mention his name in this board without some commentators losing their minds.  

Trudeau has too few experienced political heavyweights in cabinet.  His bench strength is weak.  Sajjan (I planned the operation myself), Bennett (the MMIW Inquiry is on track) and Hussen (Our immigration system is under control) are cases in point.  

It's good management to take full advantage of experience (Mr. Goodale too).
