I see that ConservativeHome are reporting two polls from Oldham East & Saddleworth which show a modest Labour lead as evidence that Labour will win a 'thumping' victory.
I would take this interpretation with a pinch of salt.
I well remember during the Hartlepool by-election in 2004 that an NOP poll for Channel 4 put Labour a whacking 33% ahead. The actual result? Labour won by only 6%.
And it would have been less if the poll hadn't put Lib Dem helpers off from coming to help!
There was a similar poll, IIRC, in Birmingham Hodge Hill.
Parliamentary by-elections are all about momentum, and a lot of that is created by the sheer amount of effort that goes in during the last few days of the campaign.
We now have clear evidence to show local voters that the election is a 'two horse race', and this is likely to help us narrow the gap sharply.
Reports from the campaign are good. I would urge you to get along and help if you possibly can.
