Republican House members overwhelmingly come from districts that have high percentages of married people and lots of children. . .
Many Democrats represent areas that have many single people and relatively few children. Democratic districts that have large numbers of children tend to be predominantly Hispanic or, to a lesser extent, African-American.
This “fertility gap” is crucial to understanding the differences between liberals and conservatives, says Arthur Brooks, a professor of public administration at Syracuse University. These childbearing patterns shape divisions over issues such as welfare, education and child tax credits, he says.

Always Question Authority 
Aaaaand the article doesn’t explain it at all. In fact, it repeats without evidence that a “traditional marriage” is the best kind of family for kids to grow up in, when recent statistics show that the best family for kids to grow up in is actually one with two homosexual parents, which may be “traditional” in the sense of “two parents around”, but would hardly be considered “traditional” by the sort of person who says things like “traditional marriage”.
Sad.
Huh. I’m loading the original page now, but I can’t understand how anyone could say “I have a lot more children, and therefore I don’t want a social safety net.” That seems backwards to me — if I had a lot of children, I’d want there to be as much support for them as possible.
For that matter, right-wing support for war also seems ridiculous by that standard: “please, turn as many of my children as possible into cannon fodder!” There had better be a really good explanation for this…
