A recent Clinton campaign research document charged that Barack Obama was falsely claiming to be a professor:
Sen. Obama consistently and falsely claims that he was a law professor. The Sun-Times reported that, "Several direct-mail pieces issued for Obama's primary [Senate] campaign said he was a law professor at the University of Chicago. He is not. He is a senior lecturer (now on leave) at the school. In academia, there is a vast difference between the two titles. Details matter." In academia, there's a significant difference: professors have tenure while lecturers do not. [Hotline Blog, 4/9/07; Chicago Sun-Times, 8/8/04]
Today, the University of Chicago released the following statement:
The Law School has received many media requests about Barack Obama, especially about his status as "Senior Lecturer." From 1992 until his election to the U.S. Senate in 2004, Barack Obama served as a professor in the Law School. He was a Lecturer from 1992 to 1996. He was a Senior Lecturer from 1996 to 2004, during which time he taught three courses per year. Senior Lecturers are considered to be members of the Law School faculty and are regarded as professors, although not full-time or tenure-track. The title of Senior Lecturer is distinct from the title of Lecturer, which signifies adjunct status. Like Obama, each of the Law School's Senior Lecturers have high-demand careers in politics or public service, which prevent full-time teaching. Several times during his 12 years as a professor in the Law School, Obama was invited to join the faculty in a full-time tenure-track position, but he declined.
