A new Survey USA poll shows Minnesotans favors the marriage amendment 51 percent to 40 percent. Local ABC News reports:

The vote on the gay marriage amendment in 2012 could be a close one, according to our exclusive new SurveyUSA poll. In our survey of 552 registered voters on May 23 and 24, 51% say they support the amendment defining marriage as between one man and one woman. Another 40% say they oppose the amendment, while 8% say they wouldn't vote on the issue and 2% are undecided. This is a significant change from our last poll in March when 62% favored the amendment banning gay marriage and 33% were opposed. Both sides anticipate multi-million campaigns, including television and radio ads and a major social media effort.
