WASHINGTON – When Bishop William Skylstad of Spokane was elected president of the U.S. Conference of Catholic Bishops this week, his margin of victory was unusually close. Members of this group, which consists of the nation's Catholic hierarchy, traditionally cast their ballots for the vice president, a position that Skylstad, 70, has filled for the past three years. Although none of the nine other candidates vying for the leadership came close to beating Skylstad, Spokane's bishop won on the first ballot with only 52 percent of the vote.
