Washington, DC — President Obama’s second Inaugural address was clearly driven by this haunting passage from his first address four years ago:

“On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord. On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn-out dogmas that for far too long have strangled our politics. We remain a young nation, but in the words of Scripture, the time has come to set aside childish things.”
