Federal health officials have their work cut out for them to convince the uninsured that ObamaCare discounts can make medical coverage affordable. New survey data released Thursday found that a majority of people — 53 percent — who were eligible for financial assistance but still remained uninsured in 2014 said the price of health coverage was the main reason. Many eligible people who remained uninsured also did not research their coverage options, according to the survey, conducted by the Kaiser Family Foundation. Fifty-nine percent never shopped on their state's marketplace, HealthCare.gov or through their state's Medicaid agency, they said.
