ComRes was not a rogue
Lots of Tories wrote off the last ComRes opinion poll - the one showing a 1% Tory lead - as a rogue. Looks like they were wrong as a new ComRes poll tonight shows almost exactly the same figures - Con 37% (unchanged), Lab 36% (unchanged) and LDs 14% (-3%) - which would deliver a Commons majority of about 20 for Labour.
This all seems to tally up with what I'm finding as Agent in a council by-election in a marginal ward at the moment (albeit a Lab vs Green marginal). The seat in question is a mix of two different types of what have historically been core Labour territory - very ethnically mixed streets with some council estates, and then an area of "Guardian-reader" territory (I live there and I read the Guardian!). I've inputted canvass data from about 10% of the electors in the ward recently and it all shows either our core vote holding up or previous undecideds and supporters of other parties moving in our direction. On the estate we hit today a team of 8 of us working for two hours failed to find anyone admitting to supporting another party.
I'm not saying that the final result will reflect that, but for now at least the picture seems to be Labour supporters rallying round the flag.
