The pep-rally atmosphere was inappropriate and disconcerting, but President Obama turned in a magnificent performance. This was a non-accusatory, genuinely civil, case for civility, in stark contrast to what we’ve read and heard over the last few days. He subtly rebuked the Left’s finger-pointing, and rose above the rancor of both sides, exactly as a president should. Tonight, he re-captured some of the tone of his famous 2004 convention speech. Well done.
