A plurality of Ohioans believe gay marriage should be legal in the state.

According to a Public Policy Polling survey of 551 Ohio voters conducted between August 16 and 19, 48 percent of respondents support marriage equality, while 42 percent remain opposed. Ten percent said they weren't sure.

The survey is the first from PPP to find plurality support for gay nuptials in Ohio.

“For the first time ever PPP finds a plurality of Ohio voters in support of gay marriage – 48% favor it to 42% who are opposed,” Tom Jensen wrote in releasing the survey. “There's been a massive shift in attitudes over the last two years – in October of 2011 we found only 32% of voters supporting it and 55% percent against. Younger voters in particular are sparking the movement toward acceptance of same-sex marriage – those under 45 favor it by a 64/48 margin.”

Pollsters also found that 69 percent of Ohioans support either marriage (44%) or civil unions (25%) for gay couples, including a majority (54%) of Republican voters. Twenty-seven percent of respondents said that there should be no legal recognition of a gay couple's relationship.
