When I was canvassing not just in 97 but in the years running up to that election people had a clear idea of what Labour stood for and were choosing Labour rather than simply voting against the Major government. To be fair, people were pretty clear on what they thought Corbyn stood for - they just didn't want him. The only Labour policy which pretty much everyone knows is around identity politics
I was a keen Blair/Labour supporter but in 1995, i didn't have a clue what they stood for, only that they weren't the Tories, it was all general ambitions, if you can link to specific Labour policies from say 94 or 95 i'd been keen to be proved wrong.
Blair said very little on specific policy until late 96/97.
TBF as well, Corbyn came very close to winning in 2017, his ideas were not that outrageous then but 2019 was a Brexit one and Labour had a very confused policy and their other policies were, at best, rather silly, like free internet for all, so tax payers give their money for the well off to have fibre broad band?
They over promised but they'd have lost regardless, it was a "Get Brexit Done" GE (3 word slogans are all we can manage)
Labour do not have a policy on id because the manifesto hasn't been written but the Tories have opened up many more NHS gender clinics to enable Self ID.
I see the Tories are already getting their 3 word slogans out there "Stop the Boats"
