I raised it with a Labour Party canvasser a couple of weeks ago. After bending her ear for a while she conceded that she didn’t know the views of the candidate on the issue, so took my phone number so the candidate could call me to discuss. And to my surprise a week later, the candidate called.
After I was just getting started she stopped and said that she remembered me raising it when she was canvassing for our labour mp before the last GE! Which was pleasing, although could just mean i’ll be blacklisted and avoided by all LP canvassers in the future.
To her credit, she let me go on about it for ages (once you get started, there’s a lot to say), and seemed to be listening. It was clear that she hadn’t really given it much thought, beyond let’s be kind. At the end, she conceded that I had made many very good points, and it was difficult to argue against any of them. Of course, this counts for nothing if she’ll just keep quiet about it and tow the party line. But there’s probably little opportunity to do anything about it at local council level anyway.
But, as PPs have said, every little counts, hopefully.
