Real talk, the purpose of the party is to represent the views of the voters. Not it's members. Otherwise Labour would have a new leader by now.
A party represents its members views, and presents them to the voters. Unfortunately, it seems like a sizeable proportion of the PLP doesn't agree with their members and isn't willing to listen to them - they'd rather drag the party through the mud and ensure the headlines are about infighting rather than actually opposing the party in government.
