Double blow convulses Republican bid to reform US health care

US Senate Republicans suffered a second stinging setback in as many days Wednesday in their drive to uproot Obamacare, when a plan to repeal the health care law -- with no replacement at the ready -- failed to advance in the chamber.The washout has left Republicans -- who only a day early rejoiced when the Senate agreed to proceed to a formal debate on health care -- struggling to find consensus on how to fulfill President Donald Trump's pledge to scrap the 2010 Affordable Care Act.
