Fault Lines' Avi Lewis takes a look back at the promises that swept the US president to power - and Americans' perceptions of Obama the man, the policy-maker, and the commander-in-chief at the end of his first 12 months in office.

As the desires the nation projected onto Obama begin to dissipate, Avi Lewis talks to backroom powerbrokers from both parties, one of the country's most influential cable news hosts, die-hard Obama fans who poured their hearts into the campaign, and a mall full of Republicans at a Sarah Palin book signing.

And he finds a populace reflected in its images of its own president: a United States of America fragmented, fractious, often fearful - yet still somehow propelled by hope.
