Minnesota voters are divided on a proposed amendment which would ban gay marriage in the state.

According to a Public Policy Polling survey of 824 likely voters conducted on September 10 and 11, 48 percent of voters favor the amendment, while 47 percent remain opposed.

“It looks like Minnesota's marriage amendment will go down to the wire,” Dean Debnam, president of Public Policy Polling, said in releasing the poll. “Voters in the state are very closely divided in their attitudes about it.”

A majority of Democrats and voters under 45 oppose the ban – 78% and 50%, respectively – but Republicans (80%), independents (51%) and seniors (53%) support it.

Seventy-two percent of voters support either marriage (40%) or civil unions (32%) for gay and lesbian couples. Twenty-five percent say there should be no legal recognition of a gay couple's relationship.

A poll released earlier this week found greater support for the ban. The survey commissioned by ABC affiliate KSTP and conducted by SurveyUSA found 50 percent of Minnesotans favor passage of the amendment, while 43 percent object.
