Via Townhall, Reuters reports Obama claims to be against same-sex marriage, but also against the federal Defense of Marriage Act (DOMA) or any other effort to defend the traditional definition of marriage:

She [Michelle Obama] said he [Barack Obama] supported a complete repeal of the federal Defense of Marriage Act, or DOMA, which only recognizes marriages between men and women and upholds states' rights not to honor same-sex marriages performed elsewhere. He also opposes a "don't ask, don't tell" policy toward gays in the U.S. military and was against a constitutional amendment to ban gay marriage, she added.

He supports full family and adoption rights for gay and lesbian couples and believes the federal government should not stand in the way of states that opt for domestic partnerships, civil unions or civil marriage, she said. The Illinois senator opposes same-sex marriage.

But that last sentence is ridiculous, totally contradicting all the previous content of the story. He does not oppose same-sex marriage. It's obviously a lie to say he opposes same-sex marriage. He might say he opposes it because his view isn't politically popular, but that's just a matter of cowardice and dishonesty. Barack Obama favors the radical redefinition of marriage. He should just be honest and say so.
