As a professor at Northern Virginia Community College, Jill Biden might be the first wife of a vice president to hold a paying job while her husband is in office, but will she be granted the honorific “doctor”? She holds two master's degrees and she received her doctorate degree in education in 2007. She prefers to be addressed as "Dr. Biden," but many, including newspapers, only use the title for those in a medical profession. Vice President Biden joked on the campaign trail that his wife's ambitions were fueled by ulterior motives: "She said, 'I was so sick of the mail coming to Sen. and Mrs. Biden. I wanted to get mail addressed to Dr. and Sen. Biden.' That's the real reason she got her doctorate," he said.
