Most progressives are more liberal or centrist, or left leaning but not full left. I suspect the call from the left to encourage progressives is more to add numbers and ensure a labour victory... And this is fine. Because no progressive thinks that having this mess of the Tories is better than labour. The only thing progressives ask, is for electoral reform to be on the agenda and to avoid enabling the Tories again in future.
It's a call to arms against by progressives against an austerity programme led a by an establishment keen to continue the movement of wealth from poor to rich.
