The Challinor thing, you mean? Dreadful mate, but it's one person not a whole party...
If there's one thing that I'm certain never happens, it's that working people who aren't genuinely interested in politics (i.e. the majority of them), read party manifestos.
Hence the usual trite bollocks about loony lefties etc.. when Corbyn's policies (for example) were generally very popular.
Boris got in because of three words "Get Brexit Done". No one really knew what the fuck that meant, least of all that lying, corrupt fuckwit, but it was nice and simple.
This time Starmer will get in because of five words, "It's time for a change". Most people won't have a clue what that change will be either, including that dissembling, vacuous, twat. But again it's nice and simple for people who don't want to think too hard.
Here's my prediction: Under Starmer, very little will change, and in five or ten years we'll likely be back under a "rehabilitated" Tory government (having had a period where they couldn't screw anything else up).
I've actually mislaid my postal vote, which is this town is no great loss. If I went with anyone though, this time it would probably be Green.
