Obama backs Maine’s same-sex marriage measure

President Barack Obama is wading into Maine’s same-sex marriage campaign with an endorsement of Question 1, the ballot measure that would legalize same-sex marriage in the state.

“While the President does not weigh in on every single ballot measure in every state, the President believes in treating everyone fairly and equally, with dignity and respect,” Obama’s northeast regional press secretary, Michael Czin, said in a statement. “The President believes same sex couples should be treated equally and supports Question 1.”

While Obama wasn’t a same-sex marriage supporter when he came into office in 2009, he announced in May that he supports same-sex marriage rights, a week after Vice President Joe Biden said he was “absolutely comfortable” with same-sex marriage.

In an interview with ABC News, Obama said his decision to support same-sex marriage represented an “evolution” in his thinking on the issue.

Three other states have same-sex marriage measures on their ballots this fall. Voters in Maryland will decide on a measure similar to Maine’s, while Washington voters will decide whether to uphold a new state law legalizing same-sex unions. In Minnesota, voters will decide whether to approve a constitutional amendment banning same-sex marriage.

The Washington Post reported Thursday that a pro-same-sex marriage ad in Maryland highlights Obama’s support for gay couples’ right to marry.
