A vote Tuesday on whether Anchorage should add sexual orientation and gender identity to the Anchorage Equal Rights Initiative might be close.

Polling conducted by Dittman Research Communications found that 50 percent of the 500 voters surveyed support the measure, while 41 percent said they were opposed. However, 9 percent of respondents said they remain undecided.

If approved, the proposal would override Mayor Dan Sullivan's 2009 veto of a similar ordinance approved by the Anchorage Assembly.

A series of ads urging voters to reject the measure have been criticized by supporters.

“As many people predicted, here in the last days of the campaign ads on the Internet and Facebook against Proposition 5 have taken an ugly turn. They depict unacceptably offensive and intentionally stigmatizing distorted cartoons of gay and transgender individuals. Such dehumanizing stereotypes do not represent the values that we share as a community,” former Governor Tony Knowles said during a press conference.

In one 30-second ad from Protect Your Rights – Vote No On Prop 5 titled Steve's Gym, a female narrator says that Prop 5 would force gym owner Steve to “open the women's locker room to anyone who claims a female identity.” The cartoon customer is drawn to look like an unshaven, hairy chested man with pink lipstick and a pony tail.

“If Steve says yes, he'll lose customers,” the narrator is heard saying. “And if he says no, he can be fined or imprisoned.” (The video is embedded in the right panel of this page. Visit our video library for more videos.)
