In November 2012, Minnesota voters rejected a constitutional amendment that would have defined marriage as only between one man and one woman, which would have blocked a judicial or legislative path for same-sex marriage. At the same time, voters elected a majority DFL legisature, which has now voted on legislation to legalize same-sex marriage. This map compares the will of the voters as seen in November 2012 with how legislators voted in May 2013.
The wording of the constitutional amendment up for a vote in 2012 meant that voting "Yes" was a vote to keep marriage between one man and one woman. The vote by the legislature to legalize same-sex marriage is the opposite; "Yes" votes to legalize same-sex marriage.
