In this “How Would You Fix It?” interview, Julie Rovner, KFF Health News’ chief Washington correspondent and host of the What the Health? podcast, sat down with David Blumenthal — a physician, health policy expert, former Obama administration official, and author — to explore the dynamics that make fixing the nation’s health care system so difficult.

They discussed the pivotal role the president of the United States plays in health policy — whether it is building support for or opposition to new plans and proposals. “Presidents have a level of authority which is often underappreciated, especially in health care,” Blumenthal said.

Blumenthal and Rovner also discussed the historical reasons the U.S. has been unable to enact universal health care, incrementalism versus sweeping change, and what he described as “the dance” between proponents and opponents — usually a clear party-line split between Democrats and Republicans — of major health care reforms.

Today, the split seems to have come to a head, as public health, science, and expertise are being viewed by one end of the political spectrum as “the opposition,” Blumenthal said, which will complicate efforts. Still, he outlined ideas for moving forward.

An abbreviated version of this interview aired April 23 on Episode 443 of What the Health? From KFF Health News: “RFK Jr. vs. Congress.”

Blumenthal’s latest book, Whiplash: From the Battle for Obamacare to the War on Science, co-written with James A. Morone, offers a behind-the-scenes look at how three presidential administrations pursued very different health policy goals.
