David Blankenhorn, a self-described liberal Democrat, comes out forcefully against recognizing same-sex marriage in a book being released today. Blankenhorn heads a think-tank called the Institute for American Values, and has written much on the effects of fatherlessness in families.

I haven't read the book yet, but Blankenhorn is as smart and articulate as they come in the ongoing national debate over gay marriage. His book should be well worth a look from anyone who follows the issue closely.
