Corbyn has achieved a remarkable amount, and what's interesting in the UK is that figures like Corbyn tend to highlight the ugliest aspects of our political system and media just by existing. The electorate response was not as simple as "lol nope", it took a concentrated campaign to paint eminently sensible and popular policies as tethered to someone who was inept, a security risk, a racist antisemite, a terrorist sympathiser, a communist, a poor dresser, whatever else. Every personality-based and emotional provocative button had to be pushed in a very cynical fashion, and it was so explicit that large sections of society can either no longer ignore it, or have caught onto the game for the very first time. I imagine it was pretty eye opening to the younger generation.
This kind of thing is hard to measure, but what Corbyn and the 2019 version of Labour represented probably isn't going to die, but take a new form. This can go one of many ways, and I think the worst would be to follow in the footsteps of the U.S., where electoral politics becomes increasingly meaningless in terms of economic policy and the public who do bother to vote simply go for whoever makes them feel good -- a comforting Reagan, an angry Trump, an amusing Boris Johnson.
>>6357 When it comes to economic policy electoral politics in Britain has been mostly meaningless since the late 1980s. I would specifically date it to when Labour internally agreed to back entry to the European exchange rate mechanism (despite their tiny rump of Eurosceptics winning the argument that it was a terrible idea) because despite the fact it was obviously a terrible idea Labour felt the best way to buy economic credibility with the electorate was to copy the Tories inept economic policy.
(Cynically, perhaps they were right: When the ERM imploded who remembered that Labour's policy was the same?)
2017 is a possible exception where the electorate got a real and viable choice for change (if you only look at the polls and the result) but I find it hard to believe Labour would've actually voted through its own budgets had it won.
