$5.2 billion for just 364,682 enrollees. In her testimony before Congress today, Health and Human Services Secretary Kathleen Sebelius provided an updated dollar amount for the cost of HealthCare.gov: $677 million. In addition to the $677 million spent on the federal Obamacare website, the Centers for Medicare and Medicaid Services (CMS) have shoveled $4.5 billion of taxpayer money to promote Obamacare on the state level. HHS says 364,682 people have selected a plan. That means the taxpayer cost per enrollee is over $14,000. ($4.5 billion + $677 million = $5,177,000,000 ÷ 364,682= $14,196)
