Yesterday, Joe Biden demonstrated unequivocal support of gay marriage:

"I am absolutely comfortable with the fact that men marrying men, women marrying women, and heterosexual men and women marrying another are entitled to the same exact rights, all the civil rights, all the civil liberties," Biden said on Sunday, "And quite frankly, I don't see much of a distinction— beyond that."

The New York Times insists that Biden was off-script in his endorsement of gay marriage. But Slog tipper Gale points out that Secretary of Education Arne Duncan also strongly supported gay marriage on Morning Joe (1:15 to 2:00 in this video) and this doesn't seem like it could possibly be a miscalculation. With North Carolina's bigoted anti-gay-marriage amendment dominating every news outlet in the United States, how could the Obama team not have prepped the vice president for a question on gay marriage?

President Obama, reportedly, is still "evolving" on the issue, and Biden was clear about the fact that the president, and not the vice president—is the one who establishes policy. But this seems awfully undisciplined for a campaign that has prided itself on its discipline. What do you think?
