Gore Speaks Out on Gay Marriage

AL Gore:

"Gay men and women ought to have the same rights as heterosexual men and women -- to make contracts, to have hospital visiting rights, to join together in marriage, and I don't understand why it is considered by some people to be a threat to heterosexual marriage," he says on the video, which appears on his Current TV network. "Shouldn't we be promoting the kind of faithfulness and loyalty to ones partner regardless of sexual orientation?"

The leading Democratic presidential candidates have tiptoed up to, but not crossed, the line of support for same-sex marriage. All three support equal substantive rights for gay and lesbians couples but, for the most part, have tried to have it both ways on the issue.
