Of course it could. That doesn't invalidate it, though. Any more than the seats Labour gained by the election are invalid because of it. My only point is that the febrile nature of politics at the moment makes any grand claims of vindication from the Labour party dubious in the extreme.
To be fair to Berni, literally the entire country was of pretty much the same view. Even the pollsters who had Lab and Con neck and neck on election day were highly dubious about their own stats.
Saying that, I started worrying months and months ago when Corbyn started talking about harnessing social media. So as with football, it turns out I am Awimb's true political sage.
