Presenter Matt Frei talks to David Plouffe. After managing Barak Obama's successful campaign for President, David Plouffe is back to work pushing for "change", but this time the White House is hoping he can put his 2008 magic to work for the Democratic Party's midterm election campaign. In 1962 the Mormon Tabernacle Choir demonstrated a new style of international diplomacy when it reached across the Iron Curtain to perform the world's first international satellite television broadcast in front of Mount Rushmore. Two members of the choir recall what it was like to send music across enemy lines and reflect on the changes they thought might be possible. Matt Frei talks to Noam Chomsky. Over 40 years, he's explored ideas of war, conspiracy, conservation and communication. Americana asks him how his ideas have changed over time and how Americans may continue to transform in the future.
