In this July 19, 2012 file photo, Vice President Joe Biden campaigns at the Plumbers & Pipefitters Local Union 189 in Columbus, Ohio. In May, after Joe Biden tripped up his boss by voicing support for same-sex marriage while the president remained on the fence, there was speculation about whether the remarks were spontaneous or deliberate.
