An article on PBS's Frontline Web site states, "In 1993 just about half of women between the ages of 18 and 29 said abortion should be available to anyone who wants it, according to a CBS/ New York Times poll; 10 years later, in 2003, the number of young women who felt that way dropped to 35 percent." I've searched the NYT on Lexis-Nexus and I can't find any articles that refer to the poll. How can I track down the original data?
