A poll released Thursday found increasing support for gay marriage among Pennsylvania voters.

According to a Public Policy Polling survey of 504 Pennsylvania voters, the state is nearly evenly divided on the issue, with 45 percent of respondents saying gay nuptials should be allowed and 47 percent opposed. Eight percent refused to answer.

Support has increased 9 percentage points since a November, 2011 poll taken by the firm.

Voters under 45 support marriage equality 58-35, while seniors remain opposed 62-28.

“The massive generational gap on gay marriage in Pennsylvania reflects what we see [in] most places,” Dean Debnam, president of Public Policy Polling, said in releasing the findings. “Majority support for it is just around the corner.”

When given the option of civil unions, an overwhelmingly number (74%) of voters are either in favor of marriage (38%) or civil unions (36%). Only 24 percent oppose any legal recognition for gay couples. Sixty-eight percent of Republicans support one or the other.
