Interest Group Scores for Congress

Over on the Polmeth listserv, Charles Stewart of MIT posted a great compilation of interest group scores for Congress. ┬áHere’s what he said:

Thanks to everyone who sent me leads about updates to the ICPSR ADA/ACU datasets. Here’s the best information I found.

There are two datasets with long time series, both of which have links off my congressional data page: http://web.mit.edu/17.251/www/data_page.html

The Sarah Anderson/Philip Habel dataset has nominal and adjusted ADA scores for 1947 to 2007: http://habel.siuc.edu/data/

The Tim Groseclose site has a number of adjusted and nominal interest group scores from 1947 to 2008: http://www.sscnet.ucla.edu/polisci/faculty/groseclose/Adj.Int.Group.Scores/.

Go to town!
