Opposition to gay marriage in Nebraska has lessened, a new study has found.

During an Omaha stop of the Human Rights Campaign's (HRC) 17-city On the Road to Equality bus tour, the group announced the results of a new survey conducted by the Greenberg Quinlan Rosner Research group.

A narrow majority (51%) of Nebraskan's oppose marriage equality, while 42 percent said they support it. But in Omaha, the state's largest city, supporters outnumber opponents. Fifty-four percent of respondents said they support giving gay and lesbian couples the right to marry, while 40 percent were opposed.

Nebraska voters in 2000 overwhelmingly (70%) approved a constitutional amendment that bans such unions.

Pollsters contacted 616 Nebraska adults for the survey, which has a margin of error of plus or minus 4 percentage points.

Dave Bydalek, executive director of Family First, a group that campaigned for the gay marriage ban in 2000, told the Omaha World-Herald that he was skeptical of the poll's results.

“While there no doubt has been some sort of change in attitude, I would be skeptical of such wholehearted reversal,” he said.

The HRC bus will visit the ConAgra campus in downtown Omaha on Saturday and the Memorial Stadium at the University of Nebraska-Lincoln on Sunday.
