Presidential candidate Bernie Sanders proposed a single-payer system to replace all current health coverage. His system would cover all medically necessary care, including long-term care, without cost-sharing. We estimate that the approach would decrease the uninsured by 28.3 million people in 2017. National health expenditures would increase by $6.6 trillion between 2017 and 2026, while federal expenditures would increase by $32.0 trillion over that period. Sanders’s revenue proposals, intended to finance all health and nonhealth spending he proposed, would raise $15.3 trillion from 2017 to 2026—thus, the proposed taxes are much too low to fully finance his health plan.
