Roper Center just added the CBS/NY Times Tea Party Movement Poll dataset: "From April 5-12, 2010, CBS News and New York Times interviewed a sample of national adults including an oversample of Tea Party supporters about their views on the current state of government and the economy. The study includes a series of questions about the respondents involvement with the Tea Party, as well as views of the movement."
You can also generate crosstabs on this dataset before downloading by using RoperExplorer, the new online data analysis system. Want to see the percentage of tea party supporters by gender, age, or race? Simple enough. Questions about using the dataset or RoperExplorer? Just ask Lynda!
