President Donald Trump and Republican congressional leaders have been working overtime to convince those among their own ranks to vote yes on a controversial proposal to repeal and replace the Affordable Care Act. Breaking with his party, Governor Charlie Baker sounded the alarm yesterday in a letter to the state’s congressional delegation, saying that if the GOP American Health Care Act were to pass, the state is estimated to lose $1.5 billion in federal revenue by 2022. The funding blow to Mass Health – the state’s version of Medicaid - would force hundreds of thousands of people to lose insurance. Joining Jim Braude ( @jimbraude ) to discuss the political and policy implications of the health care proposal are Don Berwick ( @donberwick ), who was in charge of Medicare and Medicaid for President Barack Obama when the Affordable Care Act was being phased in, and Heather Cox Richardson, a professor of pollical history at Boston College.
