The government knows they’re on the wrong side of many issues, to the point they know they can’t win an open debate.
So media control, regulation by enforcement, and institutional control becomes the focus of effort.
The only way out of this is if you successfully blame $marginalised_group for the peoples problems. Or spend decades undoing the damage, but nobody ever gets decades in power.
I appreciate this in an anecdotal but I've spoken to quite a few people I know in my family, that saw it as their civil duty to vote and they told all told me some variation of "there is nobody worth voting for", "I don't think it matters who I vote for".
I am sure many green voters felt the same way for many years and now they stand a decent chance of getting many seats!
I don't vote. There are many reasons I don't vote. However the biggest reason I don't vote is that the whole premise or at least how it is presented to you is false. The way it is presented to you both in school, media etc. is that you are supposed to read the manifesto, consider the candidates arguments and history etc. etc.
People don't do that, they vote for their team. People have their political teams, much like Premiership Football it often comes down to the "Reds vs the Blues" (literally Man U vs Man City).
