I'm afraid I don't think people today could give a damn about Keir Hardie. I wonder how many have even heard of him?
Have you read anything by current MPs such as Wes Streeting or Clive Lewis? Or followed MPs such as Debbie Abrahams, Sarah Champion or Jess Phillips on Twitter? They are doing their best to hang on to their Labour seats and, by all accounts, are good constituency MPs.
They are frequently attacked on the one hand by those on the left of the Labour Party and I don't suppose it helps that they can't count on the support of people of those within the LP, who claim to be on their side. The national media picks up on anti-Corbyn comments, which will count against them. People will respect their MPs, but be affected by the national smears.
It's unlikely Corbyn will still be leader in 2022. With a bit of luck, it will find somebody effective, but it will be too late. Voters will have chosen a government, which acts against their interests and could be landed with an MP less effective than the ones they have now.
