Evangelicals and Foreign Policy

I was at a bookstore yesterday and happened across this written piece by Walter Russel Mead in Foreign Affairs on Evangelical Protestantism and U.S. foreign policy.

I've only glanced through it real quick, but this paragraph caught my eye:

Why focus exclusively on Protestantism? The answer is, in part, that Protestantism has shaped much of the country's identity and remains today the majority faith in the United States (although only just). Moreover, the changes in Catholicism (the second-largest faith and the largest single religious denomination in the country) present a more mixed picture with fewer foreign policy implications.


Not exactly sure what Mr. Mead means by this and, unfortunately, it doesn't look like he elaborates.
