Compass don't seem to be making very much of the poll they got YouGov to do of Labour Party members.
This is not surprising when you read the detailed results: http://www.yougov.co.uk/archives/pdf/Compass-FEB09_results.pdf
Party members don't want post office part-privatisation, and are keen on a windfall tax, but aside from that their views will have contradicted Compass' soft left world view:
They overwhelmingly think Gordon Brown is doing a good job.
More of them think Lord Mandelson is going a good job than they do Harriet Harman!
Only 11% say they are "very left wing" (Hard Left?) and a further 36% "fairly left wing" (Soft Left?), whilst 50% are either "slightly left-of-centre" or to the right of that.
Younger members, women, middle class members and southerners are very slightly to the left of their older, male, more working class and more northern comrades.
A majority want to see the DWP's welfare-to-work reforms implemented.
