We will see what happens overall but my point is not about the overall result, it is about the political segregation on a geographical basisThe exit polls focus almost exclusively on the top 100-120 marginal seats, which is where elections are entirely won and lost.
There were real people standing outside polling booths in those constituencies, gathering real data on how real people had actually just voted. Therefore the outcomes in these marginals can be predicted with high statistical significance.
By contrast, for example, the first constituency to declare - Houghton and Sunderland South - was the 136th-safest seat in the whole country in 2010 (or the 514th-most-marginal). It was, and is, irrelevant for pollsters who are trying to call the election result.
