A controversial proposal in Anchorage, Alaska, that would have added protections based on “sexual orientation” and “transgender identity” to the city’s code has been handily defeated, defying a pre-election survey and proving once again that voters often say one thing on issues of homosexuality and then do another. The proposal, known as Proposition 5, failed by a margin of 58-42 percent. A poll conducted March 25-26 that used the exact language found on the ballot showed Prop 5 winning, 50-41 percent, with 9 percent undecided.
