Support for gay marriage among African-Americans in Ohio has increased 26 percentage points since President Barack Obama announced in May that he supports such unions.

According to a Public Policy Polling survey taken last fall, only 16 percent of black voters in the state favored gay marriage. Forty-two percent of respondents to a poll taken this week said they approve of such unions.

The pollster previously found similar increases among black voters in North Carolina and Pennsylvania.

“We've now found in both North Carolina and Pennsylvania that black voters have moved more toward support of gay marriage in the wake of Barack Obama's announcement,” said Dean Debnam, president of Public Policy Polling. “The media's been asking the wrong question – the big issues isn't how Obama's stance will affect his reelection hopes. It's how Obama's stance will move public opinion on gay marriage.”

Support for gay nuptials among Ohio voters has increased by net 10 points since October when 32 percent thought it should be legal and 55 percent illegal. Tuesday's poll found 37 percent in favor and 50 percent opposed.
