I'm having a bit of an issue that I hope someone here can help me out with, especially since I don't want to post this question on academics_anon. I'm specifically looking for a public opinion dataset for the past five or (preferably) ten years ranking "Issues Americans consider to be important," or something to that effect. I know such datasets are privately available, and are used in election campaign strategy, and I'm willing to buy the dataset if I have to -- but so far none of my searches (Google, EBSCOhost, etc.) have turned up anything relevant -- I keep getting results about specific issues, when what I want is a general dataset.
Does anyone have any suggestions?
