I am sure there is some juicy stuff in there for Obama to use, otherwise Romney would have come out long ago. The longer he waits the worse it would be to release them.
Not knowing what is in them I cant advise him to release them, but he sure gets points for being unprepared. He was hoping the Ryan announcement would get the media away from the subject
maybe he plans to release them after the convention and leave harry r. with egg on his face.
