The second problem is that Jeremy Corbyn’s leadership has become a “real world” issue. He’s not just been making blunders. He has been making them in ways that guarantees voters not normally interested in politics will sit up and take notice. The row over the anthem. His refusal to meet the Queen. Shoot-to-kill. Outside the supposedly airtight Westminster bubble, people are noticing what Jeremy Corbyn is saying and doing. And Labour MPs are noticing they are noticing.
