Obamacare open enrollment 2015: Monday deadline first big test for retooled Healthcare.gov

Obamacare's October 2013 rollout promised affordable health insurance for millions of uninsured Americans. But few were able to sign up in the program's early weeks, due mainly to a balky Web site that became a lightning rod for broader attacks by Republicans on the whole idea of the Affordable Care Act. Just over a year later, more than 6 million consumers have purchased health insurance, many for the first time, through HealthCare.gov and the site's performance has markedly improved. But with Monday's deadline looming for individual enrollment for 2015 coverage, this weekend marks the first big stress test since a new tech team overhauled HealthCare.gov.
