The marriage and voter ID amendments need the support of a majority of Minnesotans who vote in November to become part of the state Constitution. The latest poll shows the marriage amendment supported by 49 percent of respondents, while 51 percent back the voter ID measure.

Two new Minnesota Polls by the Star Tribune find a statistical dead head in the constitutional amendment to ban same-sex marriage, but a slight edge for support of a constitutional change that would require voters to show a government-issued photo ID.

A KSTP/Survey USA poll finds the marriage amendment favored by 50 percent of respondents and opposed by 43 percent. The amendment would have the Constitution define marriage as an opposite sex union. In addition, the voter ID amendment was backed by 62 percent and opposed by only half that number. It would require a photo ID to vote, among other election changes.

A new KSTP/SurveyUSA poll shows the battle between supporters and opponents of a ballot measure that would ban gay marriage could result in the closest statewide race on Election Day. The survey shows 48 percent support the amendment that would define marriage as between a man and woman, and 47 percent oppose it.

52 percent of the respondents in the Survey USA KSTP poll supported same sex marriage, while 42 percent opposed it. It's the first poll to show a majority of Minnesotans supporting it. Young people were especially likely to back same sex unions, with more than two-thirds supporting them.

Just two days after another poll found majority support for the Minnesota ballot measure that would ban gay marriage, another new poll shows just 48 percent in favor of it, 47 percent opposed – well within the margin of error and suggesting the vote could go either way.

A new survey from Public Policy Polling shows 49 percent of respondents reject the proposed amendment that would define marriage as only being between one man and one woman. The poll indicates 43 percent favor the amendment to ban same-sex marriage in Minnesota. Four months ago, a PPP survey showed 48 percent supported the amendment and 44 percent opposed it. Minnesota voters will decide in November.

Public Policy Polling says Mark Dayton is one of the most popular governors in the country, with 53 percent of voters approving of his work in office and just over a third disapproving. The latest survey also says a vote on a constitutional amendment to ban same-sex marriage could be close: 48 percent say they support it, while 44 percent are opposed.
