A "liberal-conservative divide" exists when it comes to whether people are happily married, according to a research brief just released by the Institute for Family Studies. "It suggests partisanship is one cultural factor linked to the prevalence, quality and stability of family life in America," wrote W. Bradford Wilcox and Nicholas H. Wolfinger. Wilcox directs the National Marriage Project at the University of Virginia and is a senior fellow at the institute, among other titles.
