In May 2009 the Maine Legislature approved a bill that would make same-sex marriage legal there. The Governor signed the bill and it was to have gone into effect in September 2009. But anti-gay marriage activists collected enough signatures to put the measure up for a public vote.
Update
Voters approved Question One at the polls. Same-sex marriage will NOT become legal in Maine.On November 3, 2009 Maine voters will decide whether or not same-sex marriage will be legal in that state. A "no" vote on Question 1 is a vote for gay marriage in Maine. A "yes" vote denies same-sex couples from marrying.
The wording of Question One is as follows:
Do you want to reject the new law that lets same-sex couples marry and allows individuals and religious groups to refuse to perform these marriages?
