In my case possibly related to my own innate tendency to Eeyoreness!
The polls look good for Labour now but I remember Neil Kinnock losing to John Major when everyone thought the Conservatives had run out of steam and couldn't possibly win after so many years in power.
Also because Labour would need a massive swing and the FPTP system is inherently biased to the Tories because Labour's vote is so concentrated in metropolitan areas.
Plus the government is successfully stoking culture wars and pandering to the xenophobic vote with their immigrant policies.
Plus what CurlewKate said about young people and trans ideology.
Plus the disenfranchisement of younger, more left-leaning voters with the new voter ID law.
Plus the entrenched disengagement of so many people who fail to vote because "they're all the same" and "they don't care about us" which is only getting worse with the Tories' continued debasement of politics.
Plus so many people saying they don't know what Keir Starmer stands for.
Plus the mainstream media being overwhelmingly pro-Conservative and actively obscuring and distorting Labour's message.
Plus 'the Left' being so stupidly, self-inflicted-woundingly factional.
Plus the fact that in the last century two thirds of the time we had a Conservative government compared to one third for Labour and I don't see any real large scale shift to more socialist principles amongst the public, despite powerful incentives to rethink.
I desperately hope I am wrong but am getting less and less convinced that Labour will triumph.
