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.

Augsburg College in Minneapolis is the second higher educational institution to publicly oppose the November ballot measure to define marriage in Minnesota solely between one man and one woman. Minneapolis-based Capella University joined the coalition to defeat the marriage amendment last month.

The battle over the marriage amendment may be the most expensive fight ever in Minnesota over a ballot initiative, the Star Tribune reports. Even actor Brad Pitt has donated money. Opponents of the measure raised more than $10 million, and supporters raised about $5 million. Supporters of the other ballot measure, a constitutional amendment that would require voters to bring a photo ID to the polls, raised about $1.5 million, and opponents raked in $2.6 million.

The top Minnesota-based executives with Thomson Reuters have come out against the proposed constitutional amendment to ban same-sex marriage. The company joins two other prominent Minnesota companies, General Mills and St. Jude Medical, in opposing the amendment.

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.

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.

Minnesota Supreme Court justices will hear arguments Tuesday about the titles of the Constitutional amendments that will appear on the fall ballot. Backers of the marriage and voter ID amendments want the court to get rid of the titles supplied by Secretary of State Mark Ritchie and restore the original titles the Legislature wrote. The court refused to extend the time limits for attorneys to make their arguments.

Congressman Keith Ellison is circulating a resolution opposing a voter ID requirement and is urging Democrats to adopt it at their precinct caucuses Tuesday. Republicans in the Legislature hope to put the issue on Minnesota's ballot in November. Ellison says Americans who don't have photo IDs should still be allowed to vote.
