And yet, to portray Christie in this cartoonish way, as so many critics do, is to vastly underestimate his skill as a politician. The most sophisticated communicators of the modern era hammer at a consistent argument about their moment and the response it demands, and they choose carefully constructed metaphors to make the choices ahead seem obvious — think of Ronald Reagan’s morning in America, or Bill Clinton’s bridge to the 21st century. And Christie’s communications strategy is about as sophisticated as any you will find in American politics right now…

Christie, it turns out, has a preternatural gift for making the complex seem deceptively simple. Last month I saw him hold forth at a town-hall meeting in Chesilhurst, a South Jersey borough of about 1,600. Chesilhurst is about half African-American, and I sensed more curiosity than enthusiasm among the racially mixed crowd as it flowed into the little community-center gymnasium. An unusually large number of folding chairs were empty. About 20 minutes after the program was supposed to start, there came over the loudspeakers the kind of melodramatic instrumental that might introduce a local newscast, or maybe an Atlantic City magic show, and in came Christie, taking his position in the center of the crowd. The theme of the week was pension-and-benefits reform, and in his introductory remarks, Christie explained the inefficiency in the state’s health care costs not by wielding a stack of damning statistics, as some politicians might, but by relating a story.

When he was a federal prosecutor, Christie told the audience, he got to choose from about 100 health-insurance plans, ranging from cheap to quite expensive. But as soon as he became governor, the “benefits lady” told him he had only three state plans from which to choose, Goldilocks-style; one was great, one was modestly generous and one was rather miserly. And any of the three would cost him exactly 1.5 percent of his salary.

“ ‘You’re telling me,’ ” Christie said he told the woman, feigning befuddlement, “ ‘that no matter which one I pick, the good one or the O.K. one or the bad one, I’m going to pay 1½ percent of my salary?’ And she said, ‘Yes.’

“And I said, ‘Then everyone picks the really good one, right?’ And she said, ‘Ninety-six percent of state employees pick the really good one.’

“Which led me to have two reactions,” Christie told the crowd. “First, bring those other 4 percent to me! Because when I have to start laying people off, they’re the first ones!” His audience burst into near hysterics. “And the second reaction was, of course I would choose the best plan,” Christie said, “and so would you.
