OBAMA: Now supports legal recognition of same-sex marriage, a matter decided by states. Opposed that recognition in 2008 presidential campaign and 2004 Senate campaign, while supporting the extension of legal rights and benefits to same-sex couples in civil unions. Achieved repeal of the military ban on openly gay service members. Has not achieved repeal of the Defense of Marriage Act, which denies federal recognition of same-sex marriages and affirms the right of states to refuse to recognize such marriages. Administration has ceased defending the law in court but it remains on the books.

ROMNEY: Opposes legal recognition of same-sex marriage and says it should be banned with a constitutional amendment, not left to states. “Marriage is not an activity that goes on within the walls of a state.” Also opposes civil unions “if they are identical to marriage other than by name,” but says states should be left to decide what rights and benefits should be allowed under those unions. Says certain domestic partnership benefits — largely unspecified — as well as hospital visitation rights are appropriate, but “others are not.”
