Los Angeles is a city of appearances but there is another LA beneath the sunny facade — a darker, more ominous city where racial segregation and extremes of wealth and poverty show the grimy underside of the American dream. LA is the birthplace of noir and gangsta rap, as well as of Hollywood musicals.
What will this almost apocalyptic moment in US history mean for the rich and the poor in the City of Angels? We set out on our trip across America beneath grim headlines forecasting financial disaster. But in the swank hotels and restaurants of Beverly Hills, you'd never know that the economy was on the edge of an abyss.

Veteran investigative journalist James Ridgeway blogs from the road.
We'll be joined by Guardian correspondents, politicians, and assorted opinion-makers as we try to understand the forces shaping the US vote in 2008. From Los Angeles to Washington DC - via the battleground states of Nevada, New Mexico, Colorado, Missouri, Indiana, Ohio, Pennsylvania, and Virginia - we'll be looking at the key issues and inviting ordinary citizens into our Truth Booth to tell us which candidate can snatch a divided and demoralized nation back from the jaws of disaster.
