So I sort of missed the Corbyn stuff while on vacation, but I feel like that's really exciting to see. He's sort of a goof and seems maybe sort of spotty on some social issues(?), but he's, like, a lefty. And he won big when he wasn't supposed to. And wasn't scared about being a lefty. I still think Brexit seems sort of odd as well, and I believe he's for it, but again, it fits in with his mindset and so he's at least consistent.
I'm more tired of the Bernie primary stuff than the Hillary won the popular vote stuff (and had real policies!), but that being said I'm over both, and so to me this is just nice to see someone who was told to neuter his lefty vibes just pitching them up and being awarded by young voters especially.
I never believe X is a blueprint for Y in another country, and I don't think what works in England will work in Alabama, but at the same time, I think it's a note to at least say "you don't have to immediately run to compromise to the right of your true beliefs" etc. to win. Maybe going hard left and staying true to it is a thing that can work, especially if Republicans stay losing and hated.
Alternatively, I know Macron was sort of seen as a betrayal of the hard left in some capacity, but maybe left-leaning policies ebb and flow to some degree depending on the country and France is looking for something different. In other words, it would be nice to get to a point where Macron is more the "right wing" choice of the spectrum and so if that's the "reactionary" response to people being unhappy with the left, it's at least safer than the shenanigans of a Trump and May and so on.
