Newsmax is carrying a front page headline that reads "Biden Apologizes to Obama for Gay Marriage Debacle":
But if you look at the Bloomberg article it links to, it carries the headline "Biden Said to Apologize to Obama for Forcing Gay Marriage Issue." And nowhere in the article does the word "debacle" appear, stating only that Biden's remarks "prompted the president to disclose his support for same-sex marriage before he planned to." Not exactly anyone's definition of a "debacle."
Obama's stance on gay marriage can be described many ways, but a "debacle" isn't one of them. That's just wishful thinking on Newsmax's part.
