Minnesotans are evenly divided on same-sex marriage about a month after state leaders legalized such nuptials, a new Star Tribune Minnesota Poll has found. The poll shows that 46 percent of Minnesotans support legislators’ efforts to legalize same-sex marriage, while 44 percent are opposed. Another 10 percent remain undecided. Factoring in the margin of error, the results show that Minnesotans remain deeply and evenly divided over an issue that has gripped the state for two years. Supporters are encouraged by a shift toward acceptance of same-sex marriage since a similar poll in late February, when only 38 percent thought legislators should change the law to allow such unions.
