Maggie Gallagher is a senior fellow at American Principles Project, and a co-author of the APP reports, Building a Winning GOP Coalition: The Lessons of 2012 and The Case for Politics: Why Conservatives Must Invest Seriously in Politics. She has been a thought leader on life, religious liberty, and especially marriage for more than 25 years.

Ms. Gallagher is the author of four books on marriage, including The Case for Marriage with University of Chicago Prof. Linda J. Waite, and her latest book, Debating Same-Sex Marriage, which she co-authored with Prof. John Corvino. After founding and running a think tank on marriage — the Institute for Marriage and Public Policy — Ms. Gallagher went on to co-found the National Organization for Marriage in 2007, which The Washington Post called the “pre-eminent organization” fighting the imposition of same-sex marriage. Her Weekly Standard piece “Banned in Boston” launched a national debate over the religious liberty consequences of same-sex marriage.
