The Medicare for America Act, introduced last December by Reps Rosa DeLauro (CT-03) and Jan Schakowsky (IL-09), is a halfway house -- or two-thirds-way house -- to single payer -- and arguably a complete route to all-payer. This bill (summary here) creates a revamped Medicare that auto-enrolls all children born in 2022; allows employers and employees to buy in; and folds in Medicaid and senior Medicare.
