The City of South Portland, Maine has approved a resolution in support of Question 1, the ballot question which seeks to legalize gay marriage in the state.

At its Monday meeting, the South Portland City Council approved the resolution with a 5-1 vote.

“The City of South Portland embraces legal equality and fair treatment for all residents, including the freedom to marry,” states the resolution. “Marriage equality ensures that the same dignity and recognition is bestowed upon all couples residing within the State of Maine.”

“Though the citizens of the city of South Portland may have varying views about marriage according to their personal or religious beliefs, it is nevertheless a fundamental and uniting principle of the city that all people are entitled to equal rights.”

Passage of the resolution makes South Portland the third city to endorse Question 1, joining Bangor and Portland, The Portland Daily Sun reported.

Marriage equality supporters are returning the issue to the ballot box after voters in 2009 narrowly repealed a marriage law approved by lawmakers with a “people's veto.” If approved on November 6, Maine would become the first state to legalize gay nuptials by referendum.

While surveys consistently show supporters leading – by as much as 22 points – pollsters caution that as a rule of thumb undecided voters generally wind up voting “no,” making the race a toss up.
