In celebration of our nation’s independence our guests include A.J. Jacobs, author of “The Year of Living Constitutionally”; UK law professors Paul Salamanca and Josh Douglas in a debate between interpreting the Constitution as it was written in the 18th century versus as a guideline intended to evolve with society and technologies; and, David Blankenhorn of the organization “Braver Angels” on the group’s efforts to host honest, civil discussions of public policy issues across today’s political divide.
