This was an audiobook narrated by Walter Cronkite. I really enjoyed it. It traced the establishment of the Bill of Rights back to the Magna Carta and discussed English common law in some detail. In addition, it discussed the basis and ratification of the amendments up until Women's suffrage. It took back to all those Poli Sci classes I took in undergrad.
This contained a lot of material that was covered in the Ratification audiobook also narrated by Walter Cronkite. It goes on, however, to cover the amendments to the constitution including those involving slavery, prohibition and the woman's right to vote. It does a good job.
