What is it like to serve in a state legislature, be the Missouri secretary of state, run for U.S. Senate, create a voting rights organization, and flirt with running for president? Our guest, Jason Kander, has seemingly done it all, with a particular focus on improving our election system and expanding the right to vote.

Since enactment of the Voting Rights Act of 1965, the law has been steadily diluted by a series of Supreme Court decisions. We take you back to President Lyndon Johnson’s speech before a joint session of Congress appealing for passage of the Act. We look at the subsequent actions of the Supreme Court, and some of our series' guests offer perspectives on why it's important to vote.
