The Effectiveness of the Purge of the Left

I was no fan of Jeremy Corbyn, and I don't think his leadership was good for the Labour Party. The thing that surprised me is how effective they're getting away with it. A good candidate should be able to stand - especially in seats where that candidate is going to be the right fit for a locality. If they haven't done anything terribly wrong, except for disagree with the leadership, there has to be space for those people.
