A new poll which shows Barack Obama leading Mitt Romney by less than the margin of error in Minnesota also shows the Marriage Protection Amendment leading. Victory will come down to turn out and who carries the momentum through to election day:

"...Among likely Minnesota voters, 48 percent support the amendment, down 1 percentage point from late last month. Another 47 percent of Minnesotans oppose the change, the same as a month ago. Just 5 percent of voters remain undecided. Minnesota law requires any change to the Constitution to capture a majority of all ballots cast. That means a ballot in which the voter skips the question is counted as a no vote, a twist that could become critical in the deadlocked race.

The sampling also found that Minnesota's faith leaders are enormously influential.

Fully 70 percent of supporters say their religious leader helped inform their decision on the question; 26 percent say their faith leader had little or no impact. Among amendment opponents, 27 percent said a faith leader played a significant role in their position.

Both campaigns expressed confidence in their ability to win.

"The history of polling on this issue shows that support for our side is always under-represented in the polls and the position of our opponents is overstated," said Frank Schubert, campaign manager for Minnesota for Marriage, the lead group pushing the measure. "If that dynamic plays itself out in Minnesota, as I expect it will, we will have a strong win." -- StarTribune
