Mainers United for Marriage, the group working for passage of a ballot question which would legalize gay marriage in Maine, announced Thursday that its fundraising has passed the $1 million mark.

According to the Bangor Daily News, the campaign also announced that a majority (64%) of its donations have come from inside the state and that its volunteers have spoken to 10,000 voters on the issue.

“The polling has only gone one way on this issue, and it continues to go up,” Matt McTighe, campaign manager for Mainers United for Marriage, told reporters at a news conference. “It's that level of support that we're seeing every day when we're out talking to our neighbors.”

A poll of 506 likely voters released last week found that 55 percent of voters say they would support a law which would permit gay couples to marry and “protects religious freedom” by not requiring clergy to perform such marriages.

The campaign working to defeat the measure, Protect Marriage Maine, had raised about $11,000 in cash by May 29. But that number does not include the group's ambitious Father's Day fundraising in which churches offered a special plate offering to support the campaign.

Marriage equality supporters are returning the issue to the ballot box after voters in 2009 narrowly repealed a marriage law approved by lawmakers with a “people's veto,” known as Question 1. If approved, Maine would become the first state to legalize such unions with a popular vote.
