Yahoo News‘ continuing coverage of the Republican efforts to repeal and replace Obamacare comes in the latest Health Care Declassified. We’ll combine our own reporting with the best insights from around the Internet to give you the latest on the future of health care in America. This was the week that the revised Republican healthcare bill was supposed to come up for a vote on the Senate floor in a dramatic showdown whose outcome was still uncertain as late as Saturday. But that changed quickly Saturday night, with the news that Sen. John McCain, R-Ariz., had emergency surgery to remove a blood clot, forcing him to rest at home in Arizona and, because the Republicans have no votes to spare, pushing back a vote on the bill for at least a week and perhaps longer. Rand Paul, R-Ky., and Susan Collins, R-Maine, have said they will oppose a procedural motion to begin debate on the proposal, meaning McConnell can afford no more defectors if he wants to move forward with repealing and replacing the Affordable Care Act.
