As readers of this site doubtless well know, you can get polls showing that the public has diametrically opposed positions on the same issue depending on how questions are worded.
The most recent example of this has been the issue of collective bargaining. Civitas says North Carolinians are against it. Andy Perrin, a professor at UNC, says they support it.
Since we ran the poll for Dr. Perrin (he wrote the questions and processed the data) we obviously would tend to think that the results from his version are more accurate. Nonetheless the discussion at both sites is worth reading.
Update: Rob Schofield also discussed this issue at the Progressive Pulse.
