Moments after Joe Biden offered his candid support for gay marriage yesterday, the White House rushed to clarify its position. "The vice president was saying what the president has said previously—that committed and loving same-sex couples deserve the same rights and protections enjoyed by all Americans and that we oppose any effort to roll back those rights," Biden's office told Politico. But for many gay-marriage supporters, Biden's comments have highlighted President Obama's failure to endorse their cause—even though many believe he supports it personally.
