I still don't see the logic. I'd be interested in objective evidence that shows people stayed away from previous elections because they thought it was a foregone conclusion.
I can't offer evidence. Just perceived wisdom. And I would presume there's some truth in perceived wisdom because the Tories keep banging on about not taking anything for granted.
Perhaps it's not wanting to sound arrogant. 1992 and Neil Kinnock prematurely celebrating and all that,
What cannot be argued is the general trend in decreasing turnouts. You touched upon some of the likely causes earlier, Dave.
For me, the steady decline in "tribal" politics correlates with the lack of diversity between the two main parties since 1997. People are fed up with the lack of choice, and under first past the post no other party was ever going to get a look-in. Tie this in to the almost presidential attitude of Blair and his influence on Cameron (arguably Blair II), and you get far more style over substance.
I can't help but think there's a link with the career politician. The politician who has no real world experience. Has never done anything except politics. They've helped out with some MP's case word. They've been a councillor. They've done a degree with Politics in the title. They all have one thing in common: next to no experience outside of politics.
Just like, funnily enough, the person who was MP for Marple from 2015 to 2017, and who is standing again now.
Back in the 1990s Channel 4 dramatised a book called 'A Very British Coup' that was published in 1982. I never read the book, but the TV series was excellent. But it's dated dreadfully. In it, a former miner/Trade Union official who lived in a Sheffield council house, became Prime Minster.
Can you image that happening today? I certainly can't.
