House Democrats on Wednesday unveiled a more moderate proposal for expanding health care coverage than M4All legislation supported by a number of the party’s 2020 presidential candidates. The Medicare for America Act, sponsored by Reps. Rosa DeLauro (D-CT) and Jan Schakowsky (D-IL), would not move the entire country into a single government-sponsored health plan. It would preserve employer-based coverage but allow Americans to enroll in an expanded Medicare plan, with caps on what people would have to pay in premiums.
