The Minnesota Campaign Finance Board published financial reports from ballot activity groups that cover a four-week period of early summer.
In the first six months of the year, Minnesotans United for All Families, the largest group organizing against the amendment, had a five-to-one fundraising advantage over amendment supporters. That pattern of strong financial support continued in early summer when the campaign added another 4,867 supporters.
Those donors added $758, 965 to the campaign’s coffers, said the organization’s Press Secretary Kate Brickman.
Seventy-three percent of the latest donations came from within Minnesota.
Minnesota for Marriage, the largest group working to pass the amendment, collected $31,558, or about 4 percent of what opponents raised.
