That's one-tenth the amount of money Minnesotans United For All Families said it spent in effort to pass the bill.
The group said last month that it spent $2 million on phone banks, television commercials and personal appeals to lawmakers.
MinnPost published a pointed statement about the spending disparity from Minnesota for Marriage chairman John Helmberger.
"It’s not surprising that they had to spend ten times more than traditional marriage supporters to convince legislators to redefine marriage and ignore their real First Amendment religious liberty concerns," Helmberger said. "It's proof that if you spend enough money you can get some legislators to do almost anything — even vote against the overwhelming wishes and interest of their constituents."
