GEORGE WILL: Why Chris Christie Matters. “Americans often elect presidents who conspicuously lack the perceived defect of the preceding president (e.g., Jack Kennedy’s youth contrasting with Dwight Eisenhower’s age, Ronald Reagan’s strength correcting for Jimmy Carter’s weakness). Christie, who exudes executive authority, is the antithesis of today’s bewildered incumbent floundering from the disappearing red line regarding Syria, to the HealthCare.gov debacle, to the Veterans Affairs scandals, to the no-one-tells-me-anything surprise about the Islamic State, to the Secret Service that cannot lock the White House’s front door.”

Even visually — and this is a theory first proposed by the Insta-Daughter, I believe — Obama and Christie are opposites: A fat white guy from New Jersey vs. a skinny black guy from Hawaii.
