For Corner readers who live in and around Raleigh, North Carolina, I’ll be speaking Wednesday at the John Locke Foundation’s Headliner Luncheon. My topic will be “The 2008 Presidential Contenders and Their Prospects.” (That includes Rudy — see below.) I’ll also be taking questions on all topics. The event is at noon at the Holiday Inn Brownstone Hotel, 1707 Hillsborough Ave. in Raleigh. Tickets are $25, which includes lunch, and you can purchase them online here .
