Senator Charles "Mac" Mathias was a lifelong Republican who won every election in a 26-year congressional career in heavily Democratic Maryland. A courageous risk-taker, Mathias led efforts to advance civil rights, voting rights, environmental initiatives to clean up the Chesapeake Bay, and establish the Vietnam Veterans Memorial. On foreign policy, he was an early critic of the Vietnam War and a consistent advocate for nuclear arms control, Middle East peace and sanctions against apartheid South Africa. His story, captured here by senior staff members, members of Congress and others, is an inspiring example of what a courageous political leader can do when he follows his conscience and is acts on principle. His remarkable career is a stark reminder of the days when the Republican Party stood for the rule of law, respect for the Constitution and a bipartisan foreign policy.
