The opposition already has PACs. In the 2010 Minnesota elections, groups opposing same-sex marriage financially supported anti-gay candidates. Minnesota has a "Defense of Marriage Act" passed in 1997 which restricts (rather than defends) marriage to one man one woman marriages. Republicans are trying to get a Minnesota constitutional amendment proposal passed which would place on the ballot a vote to oppose gay marriages (it has passed the Minnesota Senate). An amendment proposal bypasses the governor, and if passed by voters would be harder to overturn.
