Cassidy faces uphill race as RFK Jr. vaccine debate hits Capitol Hill

RFK Jr. testifies before the Senate in a high‑stakes vaccine policy clash that also pits Sen. Bill Cassidy against Kennedy’s allies. Kennedy supporters are backing Julia Letlow with a seven‑figure sum, suggesting political retaliation for Cassidy’s criticisms of Kennedy’s vaccine agenda. While experts say the vaccine issue may not derail Cassidy, the dynamic underscores a broader health‑policy clash within the race and could influence oversight of the Health and Human Services Department if Cassidy wins in November.
