This week on Need to Know, Mona Charen and I have a special guest: Myron Magnet, one of the foremost experts on New York, urban policy, and other things. (His new book is called The Founders at Home.) He tells us a little about the mayoral election in New York, and what it means. This is not a parochial issue, of course: It has implications or lessons for government everywhere. Then, Mona and I talk about a host of issues, including electoral politics, Iran, and music. Join us, if you like, here.
