Well excuse me for not answering your every beck and call.
Firstly, he did say maximum wage. He didnt say £1M, but then given the tiny number of people earning more than that (18,000) is that likely to make a difference? I mean, would there be a significant number of people who said £1M was okay but £2M wasnt? Maybe there would, but that brings me to the next point.
Secondly, the YouGov poll was just chucking some straw in the air to see which way the wind was blowing. It didnt mean much, other than to guage the landscape on some of the general issues & ideas. The poll showed strong support for some policies and little support for others.
This 75% poll on the other hand is being used to try and influence the vote in the House of Commons on a matter of war. That is vastly more important by any possible measure and using voodoo polls to try and influence the Shadow Cabinet is a disgrace in this context.
Thirdly, the methodology, which is what we're discussing here, was sound. Please read the link I made above for the difference between good polls and bad polls. Even if the question didnt tell us anything very useful, it was scientifically robust. This 75% poll is, as I say, about a useful as the comments section on a website.
The question was based on a lie though. There was no need to put that question. You could have pointed out that the question was based on a lie but you didn't. You could have responded to my criticism at the time but you chose to ignore it.
Not surprised that you try to justify anything that can be used to criticise Corbyn though.
