Thomas S. Monson, president of the Church of Jesus Christ of Latter-day Saints, has been given top honors as Slate magazine's most influential person over 80 years of age. At 82, he's a youngster compared to several others on the list. However, he is the only one to preside directly over millions of people. In the last year or so, his influence has affected people in many places. He was involved in the controversial Prop 8 vote in California, encouraging Mormons in the state to stand for traditional family values.
