Courtesy of Valparaiso University, here’s an interesting map gallery of religious affiliation in the United States. It breaks down the nation’s various religious identies (Muslim, Jewish, and various Christan subgroups) and plots them geographically. I found this one the most telling. Remind anyone of a certain election map?
Along those lines, if I were planning the religion strategy of a 2008 GOP presidential candidate, I’d focus on two groups: Baptists and Catholics. It’s nearly a 50 state strategy, except for those pesky Pacific Northwesterners.
