Interesting that so many comments focus on what may or may not be a shortcoming of Trudeau rather than the bad acts of Trump.  
Trump is playing the school yard bully - why are so many idolizing him?   What is even more disturbing is the impression that so many "Canadians" feel our policies must be set by another country just because their leader is Trump.  That says a lot about the mindset of a large chunk of society whether in the states or here
Right now he is using all his pre-electoral rhetoric to change the channel from his current bad press.  Republicans in Senate and the Congress answer to their constituents and will be the voice of reason against his tweets as time goes on.  Changes are coming but I think they will be more manageable than is now apparent.
And will those workers in Michigan and Ohio be so supportive when those promised wages and jobs move to the deep south(the new Mexico) with their "right to work" policies and wages?
