The battle to sustain democracy, which many historians and pundits consider this century's preeminent challenge, is the heart of the third show slated to air this season. Once considered democracy's bedrock, a proud model for the world, the American experiment in the constitutional government is being battered as never before and, many analysts warn, now is crumbling. The show brings together a panel of renowned voices to discuss the escalating threats to voter protections and the rule of law as well as how the country can rebuild the guardrails of democracy.
