The Heritage Foundation is hosting a series this fall called "Preserve the Constitution"--free and open to the public.
This summer, I attended Heritage's Military Voting Rights conference with my internship and had the chance to listen to speakers including Ed Meese and Senator John Cornyn (R-TX). I highly recommend checking out think tank lectures and events.
On Friday September 9 from noon-1PM, the topic of discussion is Reagan and the principles of the American Founding. Heritage is by Union Station, less than a mile walk from House offices and RNC headquarters, so if you're free, RSVP online. It should be an interesting and informative lunch break.
