It’s getting worse though.
Many years ago, when I was in university, a friend made the comment that, what the US was doing today, Canada would be doing in 20 years. The subsequent 30 years have pretty much proven him right. If anything, the rise of the internet and social media have accelerated this.
I use to vote conservative, but in the last 15 years of so, there has been a steady movement further and further right every year, until the party pretty much stopped supporting any of the things I used to agree with them on, while increasing support for all the parts I was never a fan of.
Now, we see a lot more of the conservative voters who act just like the Trumpkins, or at least Tea Partiers - disdain for knowledge and expertise, refusal to consider evidence or do math, blanket condemnations of the Prime Minister and other political opponents as being “stupid”, “terrible”, “treasonous”, and all that, without even a fig leaf of justifications supplied for any such assertions.
