An appropriate subtitle for the course name might be "David Dinkins and Friends." Each lecture, he invites 2-4 guest speakers to talk about a topic: education, health care, homelessness, budget, etc. He starts the lecture off by reading, from typed notes, a paragraph or so about the topic, then proceeds to read the bios of the speakers. Sometimes he has more to say, but not always. The list of speakers is impressive. Many are his former associates, and several are still in public service. The lectures rarely go into great depth about any one topic; it's more a survey course about "critical issues." However, it's definitely fascinating listening to the perspectives of authorities-- for examples, about crime from Ray Kelly, or about education from Joel Klein.
Expect lots of anecdotes, several pet stories of Dinkins retold over and over, and lecutures that won't put you to sleep. Sometimes, unfortunately, those currently in public office will feed you the official organizational spin on an issue, but at other times they can be surprisingly candid. Since many of these people are friends and former hires of David Dinkins, there is also quite a bit of effusive praise for the former mayor. A Q&A session at the end of each lecture, but don't be timid or you'll find yourself listening to long-winded, overzealous, stuck up grad students who think too much of themselves.
I would wholeheartedly recommend this course, not because you necessarily learn a lot, but just because it's interesting to hear these perspectives. It's also great if you're into networking. Attending lectures are a must, but you won't want to skip them anyway.
