ST. PAUL  (AP) - Opponents of Minnesota's proposed constitutional amendment banning gay marriage may be winning the money race but supporters say they're confident voters will approve it anyway.

Minnesotans United for All Families, the largest group opposing the amendment, held a five-to-one fundraising advantage over amendment supporters for the first six months of the year. It added nearly $759,000 to its coffers in the most recent reporting period, boosting its total for 2012 to about $3.8 million and its grand total to just under $5.4 million.

Minnesota for Marriage, the largest group backing the amendment, collected under $32,000 in the four-week early summer period.

But its chairman, John Helmberger, says he's not worried. He says dollars don't change many minds, and the outcome will come down to turnout.
