On the May 21st edition of Your Call, we’ll have a conversation with citizen advocate and former Presidential candidate Ralph Nader about his latest book Return to Sender: Unanswered Letters to the President, 2001-2015. Over the past decade, Nader wrote 100 letters to presidents George W. Bush and Barack Obama about everything from tax cuts to US foreign policy. He never received a response. In the 60s and 70s, letters to Presidents received media attention and sparked change. What sparks change today? It’s Your Call with Rose Aguilar and you.
