On Midday today, a look at the life and legacy of Senator Charles Mathias. He was a liberal Republican popular in Maryland for more than two decades and was known by his colleagues as the “conscience of the Senate.”

A collection of essays about Sen. Mathias has been released called Mathias of Maryland: Remembering a Lincoln Republican in the Senate. Frederic Hill, a co-editor and contributor to the collection, and Norman Ornstein, a former congressional staffer who wrote the foreword to this book, join Midday to discuss.
