Even as it faces another Supreme Court challenge, President Barack Obama's health care law has steadily reduced the number of uninsured Americans, according to an extensive survey released Tuesday. The Gallup-Healthways Well-Being Index found that the share of adults without health insurance dropped to its lowest level in seven years in 2014 as Obama's overhaul took full effect. The trend appears likely to continue, since 55 percent of those who remained uninsured told the pollster they plan to get coverage rather than face rising tax penalties. No state saw a statistically significant increase in the share of its residents uninsured.
