The YouGov polls are claiming to account for constituency balance. I don't know how much to trust them, but the fact there's so much variation in the polls is an interesting data point in itself.

My suspicion is that May's career is already over. She started with an unassailable lead that should have sealed the deal on Brexit, and she has thrown it away by running the most spectacular train wreck of a campaign in post-war British history.

She may still win, but questions will certainly be asked if she suddenly emerges from her current position with the hundred and fifty seat majority she was hoping for.

Corbyn meanwhile has become more and more credible, and has run a very tight campaign. Even the most dedicated PLP Blairites are having a hard time pretending that Yvette Cooper, Andy Burnham, or that Smith bloke could have done better.

I've never known a campaign that was more hard-fought and more polarised. The future of the country really is at stake, and there have been huge and heroic efforts to get the left message out.

It may not be enough against an institutionally biased and hostile BBC and press, but it's certainly made everyone I know far more political and far more involved than they would usually be.
