The library has a subscription to the Gallup Poll News Service which covers 2003 to the present. However, these are not datasets. We also have a print index to The Gallup poll: public opinion, 1935-1997.
The library subscribes to the Roper Center Public Opinion Archive which contains opinion polls dating back to the 1930s. We do not have access to Rasmussen data.
I am looking for your topic in these and other sources and I will get back to you. Do you need datasets or would a summary of the data be sufficient?
