Opposition to gay marriage in Kentucky has dropped 15 percentage points since voters approved a constitutional amendment banning such unions in 2004.

According to a Bluegrass Poll – conducted for WKYT-TV, the Lexington Herald-Leader, the Louisville Courier-Journal and WHAS-TV – released this week, 35 percent of voters surveyed support allowing gay and lesbian couples to marry, while 55 percent remain opposed.

The same poll in 2004 found 70 percent opposition to marriage equality.

“Over time, there is a clear movement on this issue but the majority of Kentuckians remain opposed to same sex marriages,” said WKYT political editor Bill Bryant.

“Kentuckians are still overwhelmingly opposed to the idea,” said Sam Youngman, political writer for the Herald-Leader. “But there has been some movement away from it. So a lot more of the country might be accepting of gay marriage as an issue. Kentucky isn't there yet, but it's getting there.”

A federal lawsuit challenging the state's ban is currently before U.S. District Judge John G. Heyburn II.

The poll of 1,200 adults was conducted by SurveyUSA between January 30 and February 4.
