In a non first past the post voting system, it’s less likely that 1 radical party remains in power long enough to screw up the high courts. But it can still happen, case in point Hungary and Poland.
Iirc, Orban had been in power for many years in Hungary and went for a gradual erosion of the independence of the courts. Death by a thousand cuts.
Pis in Poland only had a majority for 2 election cycles, but they needed only the first win to screw up the courts. Instead of a gradual (legalistic) takeover, they went for a bonkers hostile takeover of the supreme courts: https://freedomhouse.org/report/analytical-brief/2018/hostile-takeover-how-law-and-justice-captured-polands-courts
The eu should have kicked out both states out of the decision making process and implemented sanctions, but since that required unanimity, Poland and Hungary were essentially protecting each other from consequences. Now that pis lost in Poland, I hope that the eu takes action and prevents this from happening again.
It always takes them a bit of time to pivot talking points. I imagine that whenever a pivot is needed, there’s a bunch of drunk higher up russians having meetings to come up with new ideas, then all those ideas get thrown out there to test them, they measure clicks and responses to figure out what works and once they find something that sticks well enough, the frontline trolls will receive the new talking points and playbooks.
We’ve all see some vile attacks against Walz and especially Harris recently. But unfortunately for Trump and his foreign supporters, drunk macho fascists coming up with ideas to attack the character of a non Caucasian woman, does not produce ideas that resonate well with the democratic left. So they were unable to find something new that had enough zing and they went back to their golden classics of pushing a 3rd party and the “both sides” argument, for now anyhow.
