As the Democratic presidential hopefuls battle it out for the nomination, we turn to a central issue of the campaign: Medicare for All. In a new study, Yale scholars have found that Medicare for All will save Americans more than $450 billion and prevent 68,000 deaths every year.

The study in The Lancet — one of the oldest and most prestigious peer-reviewed medical journals — found that Medicare for All, supported by Bernie Sanders and Elizabeth Warren, will save money and is more cost-effective than “Medicare for All Who Want It, “a model supported by Pete Buttigieg. Sanders referenced the study at a campaign rally in Carson City, Nevada.
