"Even though I am a Tory I can see that it is not healthy for any party to be in power indefinitely. Every government needs a decent, effective opposition to hold them to account. That is where compromise comes from and that is a good thing."
Hear. Hear.
The truth is, though, that political parties change. The LibDems have no real echo of either the Liberal Party or the SDP anymore. And Labour is nothing like it was in the 90s, which was nothing like it was in the 80s, and so on, right back to the 1920s when one of their election proposals was no mandatory vaccinations.
It's likewise with the Conservatives. If you resurrected a 1950s Tory councillor, he'd be flabbergasted by modern Conservative councillors, thinking them, at best, Liberals or even Labour.
My feeling with Labour is that the problem goes back to Ed Balls, and his party associate membership idea (or whatever it was called), where for something daft like £3, you had a vote in the leadership election.
He basically allowed the nutty "hard-left" (though this term isn't appropriate really; they have more in common with the European authoritarian hard-right than the Chartist~Methodist~Marxist English left) vanguard to penetrate the Labour party, and they had been waiting for the opportunity for years. As soon as they climbed inside Ball's Trojan Horse, they stormed the barricades, and we ended up with a bunch of ideological hardliners causing havoc.
I don't even think Corbyn is to blame for any of it. However radical people assume Corbyn to be, he's nowhere near some of these people. He may have made some daft moves in his time, but he does think about issues carefully.
The other thing I'll mention, though this could just be my particular perspective, is that Labour lost an important reminder of its ethos and soul when Bob Crow died.
