On June 26, 2015, the U.S. Supreme Court ruled that state bans on gay marriage were unconstitutional, making same-sex unions legal across the United States.
But the road to that momentous decision was much longer than many know. In her new book, "The Engagement: America's Quarter-Century Struggle Over Same-Sex Marriage," Sasha Issenberg vividly guides us through same-sex marriage’s unexpected path from the unimaginable to the inevitable.
Sasha Issenberg is the author of three previ¬ous books, including "The Victory Lab: The Secret Science of Winning Campaigns." He is the Wash¬ington correspondent at Monocle and teaches in the political science department at UCLA.
