The fact that Palin made it through the debate without running off the stage shouting, "I can't do this!" should not obscure the fact that there was only one person tonight whom anyone with any sense—even John McCain, I imagine—would trust as President. Biden's performance was strong and, happily, gimmick free. He used no gotcha soundbites, no consultant-driven silliness—a fact driven home by the lameness of Palin's snark lines like, "Say it ain't so, Joe" and—pace, Gipper—"There you go again, talking about the past."
