I understand that - and I'm not suggesting PR is a bad idea - but it's far from a guarantee that the Tories would be out of power.That’s all true but only because of our ridiculous FPTP voting system. A true coalition, with a more equal share of the power base is a completely unknown entity in this country.
Before the 2019 election, which was odd for a variety of well known reasons, almost 200 seats haven’t changed sides since WWII (1 in 10 haven’t moved since the end of WWI and there was no Labour Party then)!
In fact, if you counted equivalent predecessor seats some haven’t changed hands since the 1800’s.
54 Tory seats haven’t moved for well over a 100 years. East Devon has been a Tory seat since 1835…..
It means that almost 14 MILLION people are, effectively, in one part fiefdoms, with no opportunity to ‘vote them out if they’re no good‘, which we are conned into thinking is democracy. It’s not…
I think a lot of the "out for ever" goes back to the kind of 80s/90s/00s results where a simple Labour+LD sum was always over 50% and at times 60%+. You either had Thatcher, or still had her spectre looming over politics, and it was obvious which side you're on. Nowadays, things are a little messier, and we're more aware that a lot of voters might be left wing economically, but not in terms of social issues.
Nowadays a six party coalition just scraping over the line, would be messy, especially if the Tories were the largest party. We also saw how the LDs got hammered for the coalition - something that is quite common for junior partners in coalitions, because they have to give up so much. It would not be a surprise if a progressive coalition with a small and messy majority, was followed by a Tory+Faragesque win at the following election. And whose to say that if PR results in a Corbynesque socialist party picking up 5%+, that the LDs won't jump into bed with a Tory party that "modernises" again?
