A measure which would add sexual orientation and gender identity to the Anchorage Equal Rights Initiative has more supporters than opponents, a poll has found.

The poll, conducted by Dittman Research and Communications Corp., found 50 percent of the 500 Anchorage voters surveyed support the proposed measure, while 41 percent are opposed. Only 9 percent said they were undecided.

The poll has a margin of error of plus or minus 4.4 percentage points.

Voters on April 3 will consider the proposal, which, if approved, would override Mayor Dan Sullivan's 2009 veto of a similar ordinance approved by the Anchorage Assembly.

Opponents of the law have argued that the proposed law would be bad for business.

“Compliance with Proposition 5 would be virtually impossible and very expensive for many businesses and organizations,” the group Protect Your Rights – Vote No On Prop 5 wrote on its website.

“Other states and cities have passed laws similar to Prop. 5, and the results have been disturbing. Armed with the new legal weapons provided by these laws, homosexual and 'transgendered' activists are challenging businesses and organizations that have traditional views on human sexuality and forcing them to act contrary to the consciences of the business owners, and contrary to their traditions and 'branding identity.'”

On its Facebook page, the group said the poll showed it had “some work ahead of us to close the gap by April 3.”

“We will win this when each and everyone of us decides to make a difference by talking to our friends, families and co-workers and encouraging them to VOTE NO on PROP 5.”
