CNN.com’s Religion Editor Dan Gilgoff documents the Mormon community of Washington, D.C., writing, “The nation’s capital has become a Mormon stronghold, with Latter-day Saints playing a big and growing role in the Washington establishment.” There are “13,000 active members within a 10-mile radius of Washington, though the area’s Mormon temple serves … 148,000 Latter-day Saints” from up and down the East Coast.
