On Midday today, a look at the life and legacy of Sen. 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 new collection of essays about Sen. Mathias by staffers who worked with him and elected officials who served with him paints a portrait of a principled man who put country above party and who served with integrity and passion. The book is 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 important new book, join Midday to discuss.

Join Hill tonight at 7:00 p.m. at the Church of the Redeemer in Charles Village for a discussion of Mathias of Maryland: Remembering a Lincoln Republican in the Senate.
