Former President Barack Obama says there's nothing wrong with Obamacare that couldn't be fixed by President Trump doing a better job of managing the health care law. Emerging Thursday from his post-presidency cocoon, on the seventh anniversary of the Affordable Care Act and the very day that Mr. Trump was struggling to win votes to repeal it, Mr. Obama took a victory lap, saying his signature law reset the terms of the health care debate, added millions of people to the insurance rolls and improved hospital care, saving nearly 100,000 lives so far. "The reality is clear: America is stronger because of the Affordable Care Act," Mr. Obama said. Mr. Trump was having none of it. "President Obama must be feeling the time is up," White House press secretary Sean Spicer said. The former president, he said, was changing the goal posts and obscuring the failures of the law, which has dominated the political debate for the past decade.
