The poll, published Wednesday, found voters evenly split, with 48 percent supporting the ban, and 47 percent opposing it.
“In January we found 48/44 support for the ban, while in June we found 49/43 opposition.”
“It looks like Minnesota’s marriage amendment will go down to the wire,” said Dean Debnam, President of PPP. “Voters in the state are very closely divided in their attitudes about it.”
The results also noted that while Minnesotans are split down the middle on same-sex marriage, they’re strongly supportive of providing same-sex couples with some form of legal rights.
The poll found that 72 percent of respondents support either marriage or civil unions, while only 25 percent were opposed to any sort of legal recognition.
Even Republicans voters, by a 51 to 47 margin, supported at least civil unions.
Minnesota is one of four states with a same-sex marriage measure question on the ballot in this presidential election year — voters will consider whether to ban gay marriage in their state’s constitution, in similar fashion to a constitutional ban that voters in North Carolina approved in May.
