One man is trying to repeal Obamacare. The other is trying to save it. As Congress returns and the health reform battle begins, this week's PULSE CHECK features two key figures on opposite sides of the Affordable Care Act. First, Rep. Phil Roe joins POLITICO's Dan Diamond (starts at the 1:40 mark) to explain his new ACA replacement proposal, which is backed by the Republican Study Committee, why he thinks Obamacare is in a "death spiral," and what he knows as a doctor who spent decades treating patients in rural Tennessee. After the break, Leslie Dach — a former top HHS official and the head of Protect Our Care, a new coalition of advocacy groups — talks about the plan to defend Obamacare (starts at the 24:30 mark), how they're judging success, and why he thinks Republicans are in "disarray." He's joined by Meaghan Smith, a former HHS official now at SKDknickerbocker. We’d appreciate your help: Please share PULSE CHECK and rate us on your favorite podcast app!
