Roughly 500,000 fewer people have selected coverage on the main Obamacare website than at this point last year, the administration reported Wednesday, meaning sign-ups continue to lag heading into the final days of 2019 enrollment. More than 4.1 million people had selected a plan on HealthCare.gov through Dec. 8, including nearly 1 million in the preceding week, as interest picked up ahead of the sixth and final week of sign-ups. The deadline for much of the country is Saturday.
