The proposition that any poll done for an advocacy group should be marked as partial to that advocacy group is just common sense. The pollster is not necessarily calling the shots in these instances; they are working for a client.
It's different if it's a neutral observer like a TV station as opposed to the LCV or Chamber of Commerce. The red hats on here CORRECTLY point it the Chamber bias all the time.
But that's different ... Chamber of Commerce polls tend to favor Republicans, whereas LCV polls tend to favor Democrats. Therefore a LCV poll is automatically more trustworthy than a Chamber of Commerce Poll. Don't you see the logic?
