On the night before the 2008 election, Barack Obama sounded a familiar mantra signaling the impending success of his once unlikely presidential bid. "We are one day away from changing America," he told a cheering Virginia crowd.
The next day, by a solid majority of 8.5 million votes, Americans elected the 47-year-old Illinois senator, and he set out to implement the "big change" for which he contended the times were right. On Tuesday, HBO will premiere a film capturing the promise and optimism of Obama's campaign. But a year later, the premise that the new approach of a new president could ensure such sweeping change no longer seems so simple.
