William Borah, the Lion of Idaho, is probably Idaho's most well known and important historic figure. He was a United States Senator for 33 years, and was involved in many of the most important discussions of the United States during the early 1900s. He was a noted isolationist, playing a big role is shutting down the League of Nations. He was known as a progressive Republican, and was a friend of Theodore Roosevelt, but also struck out on his own and took principled stances that often weren't popular. I read a biography about him written almost 90 years ago. This episode is a discussion of his life and what he did both for the people of Idaho and the United States as a whole.
