Supporters of a proposed constitutional amendment which would define marriage as a heterosexual union in Minnesota have raised $830,000 to approve the measure in November, the AP reported.

Minnesota for Marriage (MFM) announced the results of its 2011 fundraising on Tuesday. The coalition also reported that they have recruited over 10,000 volunteers in the last year.

“We are very pleased with our fundraising and recruiting efforts to date,” MFM Chairman John Helmberger said in a statement. “We have demonstrated substantial and broad-based support for preserving marriage as the union of one man and one woman. Not only have we generated a great of financial support for the campaign, we have generated incredible, broad-based citizen support by recruiting over 10,000 volunteers for our campaign. We're off to a great start.”

Other groups working to approve the amendment separately reported donations to their political funds, including the Minnesota Catholic Conference, Minnesota Family Council and the National Organization for Marriage (NOM).

Minnesotans United for All Families, the coalition of groups working to defeat the amendment, earlier reported it had raised $1.2 million, mostly in the closing quarter of 2011, from more than 5,100 people.
