Biden 'absolutely comfortable' with gay marriage - Yahoo! News: "The president sets the policy. I am absolutely comfortable with the fact that men marrying men, women marrying women and heterosexual men and women marrying one another are entitled to the same exact rights, all the civil rights, all the civil liberties," Biden said.
Obama has said he favors civil unions but has stopped short of endorsing gay marriage. However, Obama has also said his views on the issue were evolving.
An endorsement of gay marriage could help energize core Democratic supporters ahead of the November election but it could also run the risk of alienating some independent voters who hold more conservative views on social issues.
