More than four years after the law's passage, Republicans are as insistent as ever that Obamacare is destined to fail. Illustrating their commitment to taking down the law, the GOP-led House on Thursday is voting on a bill that would make a major adjustment to the Affordable Care Act. "Just because we can't fix Obamacare doesn't mean we can't start to get rid of its worst features," Rep. Paul Ryan, R-Wisconsin, chairman of the House Ways and Means Committee, wrote in a USA Today op-ed this week. The bill up for consideration Thursday is the Save American Workers Act.
