Because with the staggering increase in divorce and illegitimacy, they and their children are more likely to be recipients of such programs.

In a recent Atlantic Monthly article, Stephen Stark notes that far more women than men supported the Clinton health-care plan-because women are less likely to be covered by existing insurance plans (more of them work part-time).

Finally, women are more likely to support Great Society programs aimed at the needs of the poor—because mother-headed families tend to be poorer than father-headed families.
