As western politics and government decayed - lost moral legitimacy and functional foundations - each sort of party (kinda liberal and kinda conservative) rotted at the same rate and in the same ways.  All that is left is their PR.  Note that Trump and Trudeau both spend their time in a narcissistic haze, signing bills / laws and making low-voice speeches on ostensibly serious matters.  Both have made such a PR issue of the whole political thing that they are easily drawn into PR squabbles with equally silly people in the general information media  -  in lieu of doing anything actually connected with their jobs.

This situation was slow and a long time coming.  It is fast making a dialectic antithesis - a world of push-back.  For decades in the future, "McCarthyism," as a buzz word will be replaced with "Trumpism," and its equivalent here and elsewhere.  You can't forever stand still vigorously working your hands in your pant pockets.  People figure it out when everything falls apart.
