I see Trudeau being able to more passionately campaign to Trump about supporting, I dunno, a contraception organization in an African country most Canadians have barely heard of, than go to bat for an industry category that employs thousands of Canadians.... too boring, and the interests of stuffy old men in suits...

I think Trump won nothing - except a lot of good P.R., and the respect of even the Democratic party, with the Carrier plant effort.  (the net will be costing the taxpayer money, and ultimately didn't net save any jobs). He knows how to do the next step beyond a tweet (if only in a small way).

Can you see Trudeau arguing with a US President about a Canadian industry that that President may be threatening?  Do you think Trudeau knows how to take selfies to the next step, and actually do something?
