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".
The point clearly stands that had Reform not been a thing, 2024 would have been a conservative landslide.
What we got was a Labour landslide, what we should have got was some coalition.
It's certainly not a given that all the 2024 Reform vote would have gone to the Conservatives: a good chunk of it would have likely been disgusted abstention, another chunk to other anti-system parties (mostly of the right fringe, I suspect, but not excluding the Greens despite wild ideological differences), and likely a further (if smaller) chunk to other parties which were simply not the Conservatives (including Labour and the Lib Dems).
Edit: the best analysis on this is likely to be in the latest volume of the long-standing The British General Election of XXXX series, which has just been published online[0]. I haven't had time to look at it yet, though.
