I'm still a Corbyn supporter, and I think he's had a difficult time, having to owe up to his own goals, the goals of his grassroots movement and the goals of the old time voters and unions. This is very highlighted on the EU move; I don't think it's charitable to say that he "supported Tory policy"; the members don't mean anything when the majority of people voting for you aren't members.

So what would you have done if you were him? Go with your members and get booted out of any sensible position, or go with your voting base and disregard your members? Brexit was a hot button topic for many reasons and arguably the fact that someone is either a Tory supporter or betraying their voter base is an example of politics becoming more about principle than doing what's right.
