An Obamaian Performance

Eugene Robinson also gives Obama credit for his adult-like approach:

There were no fall-off-your-chair surprises in Obama’s speech, but many people might have been surprised by the style in which he delivered it. Obama didn’t sound like a president buffeted and beleaguered by the political fates. He sounded determined, patient, forceful, good-humored, at times even mischievous. He looked relaxed and in control. For the first few minutes, the applause was strictly partisan -- Democrats rising to clap, Republicans sitting on their hands. Toward the end, Republicans were often springing to their feet, too. Maybe they lost themselves in the moment.
