I do think there is a big risk of over-optimism from Labour about the Wakefield result, but I would not rely too heavily on the number of votes cast. The number of votes in by-elections is generally substantially lower than in general elections. Nevertheless, I do support Steve's caution that this not looking strong enough to suggest a Labour majority - or maybe not even a hung Parliament - as it stands. In addition, I think if Johnson is replaced before an election a lot of the anger against the Tories will fall away and the battles will be much tougher.
