There are many Canadians who are absolutely, inflexibly, loyal to a specific party. They may, at one point in their life, undergo a fundamental shift in their politics, and move out of one fixed camp either in another, or into ‘no party loyalty’. But from election to election their votes aren’t variable and aren’t contestable. Those voters aren’t the info battlespace on this one because they’re already a known quantity who won’t change in any major numbers.
Elections are decided primarily by the voters who don’t have fixed party loyalty, and who will actually sway their vote based on issues. That’s largely going to be the people who aren’t easily easily distracted by superficial. While there will be some voters who are undecided and who are unsophisticated enough to be easily distracted from major issues, I don’t believe that’s many. Most voters who pay enough attention to not be blindly loyal are able to pay attention to multiple things at once and to reassess our voting intentions in light of new information.
While political parties will still play distraction games as issues arise, I don’t believe it’s a particularly effective tactic. Also, one side using one issue to try to distract from another one does not mean that the issue isn’t significant and worthy of attention in its own right. Sitting members of Parliament publicly and knowingly kowtowing to the far right is a valid problem worth addressing. It is by no means the biggest problem out there, but it’s still a problem (and a problem relevant to this specific thread) that their party should firmly address.
