Calvin Coolidge was our 30th president (1923-1929). Today we take a look at his life. Was he a Christian man? Was he a faithful president as measured by his adherence to the Constitution? Was he a good speaker and was he able to convince people? Was he a progressive? Our guest is a fellow for humanities, faith and culture at The Center for Vision and Values. He has authored the new book: "Thinking Cal Coolidge: An Inquiry into the Roots of his Intellectual Life." Participants: Dr. L. John Van Til, Dan Elmendorf
