Americana: 21 Aug 11: Barack Obama's approval-ratings

This week, as Barack Obama's personal approval ratings slump to an
all-time low of just 39%, we'll ask Democrat Strategist Terry
McAuliffe whether the President can still pull off a dramatic
comeback, in the style of number 33, Harry Truman. Brother and
sister Tamim Ansary and Rebecca Pettys recall an idyllic American
childhood...spent in Afghanistan's Helmand Valley. The author
Philip Connors gives us a call from his self-imposed solitude among
the treetops of New Mexico's Gila National Forest. And Darius
Rucker tells all on going from rock band frontman...to black
country & western singer.
