As our colleague David Weigel reported, Democrats have latched onto the catchy idea of “Medicare-for-all” (also known as M4A) as a way of expressing their support for universal health care.

On a Koch-related note, the Koch-funded Mercatus Center at George Mason University made headlines this week after a new study by the Center found that the Democrats’ proposed “Medicare for All” program could lead to major savings in health care expenditures. John Cochrane of the Hoover Institution, once a staunch opponent of single-payer health care, also now believes that single payer “might not be so bad—it might not be as bad as the current Medicare, Medicaid, Obamacare, VA, etc. mess.”

“Medicare for All” study scholar Charles Blahous rebuked Sen. Bernie Sanders (I-VT) for misinterpreting his study in an op-ed on Wednesday, charging that charging that Medicare for All might cost $38 trillion, not save $2 trillion.
