Opponents of Minnesota's proposed constitutional amendment banning gay marriage seem to 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 six-to-one fundraising advantage over the main group backing the amendment from Jan 1 to July 10, according to financial reports filed this week. It raised about $3.8 million in the first part of the year to boost its grand total to just under $5.4 million.
