I am not sure that I want to go completely into methodogies here, but your opinion stated above appears to be misinformed. Becuase everyone's opinion counts in the general election, then everyone's vote counts in an opinion poll. What you are proposing is not exactly representative. If you want to go down that path, then here is what you might experience. One could argue that all of the younger people don't have the experience needed to formulate an opinion, so let's just slice out the 18-24 year olds. And the people over 65 are not in touch with everything like they should be, so they are now gone too. And let's be honest, the less wealthy are not contributing as much, so they're opinion doesn't really count either. Now, let's see if we can find a way to take out the people who live on the coasts, since the sea water has probably rotted their brains or something. Now, doesn't this start to look a little skewed? This could be used to go the other way too, so be careful what you wish for. And I guess opinions are a little as you say. How many people understand the concepts of survey design and methodologies and how best to implement them? Not as many as probably understand the high finance of the auto industry as I would guess. A lack of understanding does not mean that people cannot have opinions.
