The proposed marriage amendment to the Minnesota Constitution fell short of passage early Wednesday morning.
With 99 percent of precincts reporting, the amendment had the support of only 48 percent of voters. Support for the ballot measure trailed the combined "no" votes and blank ballots by more than 100,000 votes.
Shortly after 8 a.m. Wednesday, the main group that pushed for passage of the amendment conceded defeat.
"Despite the disappointing outcome of this election, we rejoice tonight that marriage is still marriage. We know that God has defined marriage as between one man and one woman, regardless of the efforts of some to overthrow His design," John Helmberger, chairman of Minnesota for Marriage, said in a news release.
Also on Wednesday morning, the Minnesota Catholic Conference, the public policy voice of the Catholic Church in Minnesota, issued a statement.
"Despite this setback, our efforts to promote and defend the cornerstone social institution of marriage will continue.
"Our position on the amendment was never 'anti' anyone, but 'for' marriage… MCC will continue to support and advocate for public policy that best serves all of society, human dignity and the basic rights of children. Marriage needs to be strengthened, not redefined. We look forward to finding ways we can all work together as Minnesotans to strengthen marriage and family life."
Heading into Election Day, recent polls had shown the measure a dead heat, but also showed amendment support edging downward for weeks.
