What could the YES proponents have done differently?

The LDs not only got the compromise proposal rather than a properly proportional one, but failed to secure an agreement that their coalition partners wouldn't campaign against it. With the two largest parties and most of the press against it, it was always going to be a No.

If you want voting reform, you absolutely must convince the Labour party to support it. It would be nice to get some positive press too, but the press are basically a free-floating rightwing attack faction of their own.

Maybe the example of Scotland's non-proportional result could be used to convince Labour.
