In my own humble (and admittedly partisan) opinion, I think Justin Trudeau has had a good week. First, he strongly criticized the PQ intention of banning religious headgear from Quebec government institutions etc, calling that going against Canadian values and rights (right in step with how his father would have reacted to this), and then he had the upfront, honest interview of how he had dabbled in pot even as an MP, setting off a predictable torrent from the Conservatives (which I suspect he anticipated and perhaps even wanted).
I would argue that both stances will help, not hurt his reputation with a good portion of what we call the moderate Canadian voter.. not just standing up for rights, but being onside with an issue that seems to have majority support amongst Canadians. He seems to have a certain immunity against being branded/defined by Conservative attack ads, as were his 2 LPC leader predecessors; most people know about JT and more importantly about his father’s legacy. Putting stuff like this out in the public eye will further let people make their own definition of Trudeau and make those dreaded CPC “attack” ads that will resurface perhaps less effective.
(This poll from Nanos didn’t hurt his week either – yes the election is 2 years away still, but I’d rather be in first then last).
