Robert F. Kennedy Jr. is a tangle of biographical ironies. He is an anti-elite renegade bearing the most elite surname in politics. Once feared for his left-wing radicalism when Barack Obama considered him for a Cabinet appointment in 2008, he has now been nominated to lead a major department for a right-wing administration. A notorious vaccine skeptic, Kennedy is set to direct health policy under the president who oversaw Operation Warp Speed, the country's most successful vaccine-development program.
