The increasingly costly and bitter fight over a constitutional amendment to ban same-sex marriage is a statistical dead heat, according to a new Star Tribune Minnesota Poll.
Six weeks before Election Day, slightly more Minnesotans favor the amendment than oppose it, but that support also falls just short of the 50 percent needed to pass the measure.
Among likely voters, 49 percent would approve constitutional language that defines marriage as only the union of a man and woman. Another 47 percent oppose the measure, while 4 percent are undecided. Minnesota law requires any change to the Constitution to capture a majority of all ballots cast. That means a voter who skips the question is counted as a no vote.
While passions for and against a traditional definition of marriage run strong, the poll also shows that attitudes are shifting when it comes to civil unions.
The poll shows overwhelming support for civil unions that would offer gay and lesbian couples the same legal rights as marriage. Overall, 68 percent of respondents would support civil unions while only 23 percent would oppose them. The support cuts across every demographic and party line. The poll interviewed 800 likely voters between Sept. 17 and 19 and has a margin of error of plus or minus 3.5 percentage points.
Deadlock on the marriage amendment offers the freshest proof yet that the fight stands to be among the closest, most expensive and least predictable of the election season.
Both sides said they are buoyed by the poll's results.
The slight edge for the pro-amendment side, while not outside the margin of error, shows "we are in good shape and reinforces our belief that if we execute our game plan, we will pass the amendment," said Frank Schubert, who leads that effort for Minnesota for Marriage. The other side, he said, "has not moved the needle" from a year ago, even after a months-long campaign.
