It's possible that, by the next presidential election, graduates of America's more than 700 religious colleges will have begun to blur the much-ballyhooed demarcation between red states and blue.
She calls them "the missionary generation." And "God on the Quad" author Naomi Schaefer Riley believes that as these 1.3 million young people move into the secular world, many will gravitate toward big cities in blue states - New York, Boston, Los Angeles - where their influence may exceed their number.
In 2001 and 2002, while researching her book, Ms. Riley visited 20 schools, including the University of Notre Dame (Catholic) in Indiana, Yeshiva University (Jewish) in New York, and Soka University (Buddhist) in California.
She was shocked that of all the people she met, only two tried to convert her.

At the entrance to Tatnuck Bookseller, housed in a former factory and now the largest independent bookstore in New England, pyramids of books crowd pieces of ancient machinery. "God on the Quad: How Religious Colleges and the Missionary Generation Are Changing America" is stacked off to the left. Riley seems at ease here, in a spot that was once one of her high school haunts.
She says the students she encountered in her reporting were, for the most part, thoughtful and motivated, immersed in a rigorous and demanding education. Their teachers were qualified. And learning and faith were elevated in equal measure.
"There's a common idea that religion waters down the curriculum," says Riley, who admits she herself must have set out with this preconception.
