Indeed, Mr. Kennedy, an environmental lawyer and scion of the storied Kennedy Democratic clan, is now a leading vaccine skeptic and purveyor of conspiracy theories. The idea that the press has a stranglehold on public information is a core, animating belief in the health freedom movement, which broadly opposes regulation of health practices, including vaccinations. Two political action committees supporting Mr. Kennedy were formed by people who knew him through this movement, which accounts for some of his most ardent support. Some are libertarians, searching for a standard-bearer; others are disaffected Democrats; some are Republicans looking for an alternative to Mr. Trump. Mr. Kennedy’s audience in New Hampshire of at least 250 people included at least one person wearing a Trump 2020 hat.
