I'm going to have to phrase this very carefully
In terms of what Labour voters thought they were voting for, I think some of them actively welcome the global approach that he takes. And they would have the same reaction to seeing a flag as Emily Thornberry had. That's only from some of the ones I know.
Of course there would've been an element of just getting rid of the Tories. Or perhaps people who aren't really paying attention and thought he would be another version of Tony Blair - and thought that was a good thing.
wrt to the misrepresented clip about Matt Goodwin and Manchester, I thought that kind of thing had to be reported to the electoral commission - not the police? Or does it have to go via the police first? Maybe that's the protocol.
