Years from now, historians are likely to look back upon Barack Obama's second inaugural address as a rich treasure trove for understanding his presidency and possibly the course of American politics. It wasn't as important for his rise to power as his 2004 address to the Democratic National Convention. That one propelled him onto the national stage. It wasn't as elegant as his Philadelphia speech on race relations in the 2008 campaign. That one was his rhetorical masterpiece. But the second inaugural was far more important than either in defining his political philosophy as president.
