JEFF...
I don't disagree with your numbers and analysis....But a bit like my own summary, there's no hard evidence for your own belief that
Labour won because they were marginally more successful in keeping their core vote onside than the Tories were and because only around a 1/3 of the votes they lost went to a party who had a chance of beating them.
because nobody has access to and can analyse the individual voting patterns of the 40,000 people who did vote - how they voted and why.
The great unknown is
quite how Labour were marginally more successful in keeping their core vote as you suggest if, indeed, that's what happened and the total Labour vote was not manipulated by Postal Votes as many believe. I notice that Labour says that Mahmood was not involved in the By Election, yet he was seen regularly with Forbes in the run up to the election and, even, photographed withCorbyn

But as I said yesterday, nothing will happen and the result won't be voided because ( 1 ) The Electoral Commission don't want to discover or be associated with Electoral Fraud in the UK and ( 2 ) The Government won't insist on an investigation because the Tory share of the vote will merely highlight how much The Tories have pissed off their own and swing voters by their incomptence the past six or seven years - particularly relating to Brexit.
