The City of Mankato last week approved a resolution objecting to a proposed amendment which would ban gay marriage in Minnesota, making it the 12th city to do so.

Council members voted 4-1 last Monday, with 2 abstaining, to oppose the amendment.

Minnesotans United for All Families, the campaign to defeat the measure in November, cheered the vote in a statement.

“In the face of increasingly misleading and negative tactics from those seeking to pass the marriage amendment and limit the freedom to marry in Minnesota, the decision of the Mankato City Council to oppose the amendment is exciting news,” the group said. “We applaud them for taking this bold and important stance – each time a city, business or community of faith weighs in on this debate, it sparks even more conversations about what marriage means and who should have the freedom to participate in it.”

According to a Public Policy Polling survey released in June, more Minnesota voters now oppose passage of the amendment than support it, with 49 percent opposed and 43 percent in favor.
