Marches On Washington Still Making A Difference?
Thousands are expected to attend Rev. Al Sharpton's march for jobs and justice Saturday on the National Mall. The rally is scheduled a day before the dedication of the Martin Luther King, Jr. Memorial. The nation's capital has been historically commonplace for hosting marches that express views ranging from women's equality to anti-war and animal rights. Michel Martin explores the history and the impact of marches on Washington with NPR Senior Washington Editor Ron Elving and University of Pennsylvania History Professor Mary Frances Berry.
