"Red Families vs. Blue Families"

At SSRN, GW Law's Naomi Cahn and UMKC Law's June Carbone post an abstract including this excerpt:

This Article argues that two different family systems underlie the increasing political polarization in the United States. Each system has developed its own legal structure, moral imperatives, and expectations of the state. In blue states, what we term the “new middle class morality” seeks to realize the promise of the post-industrial economy through investment in the workforce participation of both women and men. The hallmark of the new system is marriage and childbearing at later ages, with greater autonomy, more egalitarian gender roles, and reduced fertility for those who postpone family formation into their late twenties and beyond.

By contrast, the red states, which correspond to the “moral value” vote in the 2004 Presidential election, affirm more traditional understandings that celebrate the unity of sex, marriage and procreation. Driven in part by religious teachings about sin and guilt, they emphasize abstinence, and see divorce and single parenthood as moral failings. While blue families have prospered, red families are in crisis on their own terms –- red states have the nation's highest teen pregnancy and divorce rates, and the growing separation between the beginning of sexual activity and marriage makes abstinence increasingly untenable.

Does the last sentence of the second paragraph state the empirical situation fairly?  If so, how should Catholic legal theory respond?
