I have said many times over the past several months that IMO the Conservatives can't win in 2019 with any of their leadership candidates, including the winner Mr. Scheer, but Trudeau can definitely lose in 2019 and with this decision seems to be making a concerted effort to do so.

I think this issue does not break according to party affiliations.  Many people of all political stripes are offended and will very likely remember (with the help of the CPC, of course).
