A good article at The New Statesman looking at the difference in views between those who vote (UK) Labour and those who are members. This shows the perils if allowing the members to choose the leaders and policies.
- Immigration top 3 concern – 48% Labour voters, 17% Labour members
- Housing top 3 concern – 29% voters, 69% members
- Believe Corbyn can win – 27% voters, 47% members
- Renew Trident – 40% voters against, 68% members against
- Labour not left wing enough – 34% voters, 56% members
So half of Labour voters are concerned about immigration but only 17% of their members, and hence if they just focus on listening to their members they will be out of touch with their own voters.
