PORTLAND, Maine (AP) — President Barack Obama is throwing his support behind Maine’s ballot question seeking to legalize same-sex marriage.

Mainers United for Marriage, the group leading the campaign in favor of gay marriage, says the Obama campaign’s regional press secretary issued a statement Thursday giving support to Maine’s gay marriage referendum on the Nov. 6 ballot.

Obama last May announced his full support for the right of same-sex couples to wed, serving as a rallying point for gay marriage supporters. But until Thursday, he hadn’t expressly given his support to Maine’s ballot question.
