“Mormons now have 39 congregations, or “wards,” in the state, compared with 15 in 1980. To the west of Boston, the only LDS temple in New England has a granite grip on a hill in the suburb of Belmont, home to perhaps the church’s most prominent member in Massachusetts: Gov. Mitt Romney.
Others among its ranks are key players in the state, including Boston Celtics president of basketball operations Danny Ainge and several noted academics, including Pulitzer Prize-winning Harvard history professor Laurel Ulrich.
Clayton Christensen, a Harvard Business School professor and church member, is convinced the region’s once hostile territory will soon host greater numbers of Mormons.”
Yeah, it would be real bad if Mitt were to lose the state of MA. in the state primaries a few years later.
You could tip an election very easily if all the Mormons are dedicated to vote for you, like we have seen them do time and time again for Romney.
