Before becoming a senator and then running for president, Barack Obama spent several years as a part-time lecturer in constitutional law at the University of Chicago Law School. I haven't read anything about what he was like as a professor. A uniter (open-minded, encouraging critical questions) or a divider (not)? Overtly ideological or dispassionate and neutral? Well-prepared or lackadaisical? Any hints about his constitutional philosophy? Inquiring minds want to know! Surely this blog has some readers who took Obama's class (or perhaps were classmates of those who did and thus at least know of his reputation), and can enlighten us.
