I'm delighted to say that Maggie Gallagher will be guest-blogging this week about same-sex marriage. Maggie is founder and president of the Institute for Marriage and Public Policy; National Journal named her to its 2004 list of the most influential people in the same-sex marriage debate. Maggie has also written extensively on marriage and family more generally; she's the coauthor of The Case for Marriage: Why Married People are Happier, Healthier and Better-Off Financially.

Maggie, as many of you know, is a leading opponent of same-sex marriage. In a couple of weeks, I also look forward to having as a guest-blogger Dale Carpenter, a law professor at University of Minnesota and a prominent proponent of same-sex marriage. (I'd thought of having them guest-blog at the same time, but decided to try a less head-to-head exchange; we'll see in several weeks how well that has worked.) Many thanks to Maggie and Dale for joining us.
