Obama's Mother

I have long thought that children from teenage mothers did about as well as they would have done if they had older mothers. When honors students have babies while teenagers the kids do just fine, and when high school dropouts have kids they do no worse than they would have had the same mother had the kid a decade later.

What I didn't realize is that we have a particularly good example of this in America. Obama's mother was 18 when he was born. Was she two months younger and in present day California, Obama's father would have been charged with a felony.
