Biden sees evolution on gay marriage

Vice President Joe Biden, increasingly visible as a key presidential adviser on domestic issues, says the country is moving toward a growing acceptance of gay marriage.

Speaking on ABC's Good Morning America on Friday, Biden compared the nation's changing views on gay marriage to the same changes he has seen on the military's acceptance of gays. "I think the country is evolving, and I think there is an inevitability for a national consensus on gay marriage," Biden said.

Biden said he agreed with Obama, who said last week that his position on gay marriage was evolving.

"At this point, what I've said is, is that my baseline is a strong civil union that provides them the protections and the legal rights that married couples have. And I think - and I think that's the right thing to do," Obama said.

"But I recognize that, from their perspective, it is not enough. And I think this is something that we're going to continue to debate," he said.
