Price controls in health care could be one of the major policy issues of the 2020 Democratic primary and a key way of differentiating the most progressive candidates on the Left from others seeking the nomination, but Republicans are posing the question as well. It should come as no surprise to find the outspoken champion for an incremental approach to single-payer health care, Sen. Michael Bennet, (D-CO), promoting government-set rates, but the fact that a Republican, Sen. Bill Cassidy, (R-LA), is joining him in leading the charge should concern conservative and moderate Republicans alike.
