Not really. He has done immense damage to the labour party that's going to take years to recover from. Assuming they can ever come back to what they were, instead of a party of minorities encouraging division.
I don't understand why people want Labour to be entirely non-effective. I don't want them in power, but I have always believed that for us to have a strong, accountable government we need a strong (NB: Not needlessly obstructive, which is sadly often what happens) opposition to keep them in check.You make a compelling argument.
