The data reported in this book represent as much as fifty years worth of polling. Over this period, enormous amounts of time, energy, and resources have gone into the effort, and our first debt is to the organizations whose efforts made the collection of the data possible.
We would also like to thank the National Data Program for the Social Sciences for access to its social change archive and for special data runs from its General Social Surveys. For the use of certain data points about abortion, we would like to thank Judith Blake. Bruce L. Peterson and Sara P. Crovitz provided research assistance. A major debt is owed to Dana Loud for her expert typing, formatting, and reformatting of the tables. Her cheerful spirit as well as expert help made the project far more bearable than it might have been.
