The total price tag for ObamaCare's main enrollment portal now stands at more than $2 billion, according to a new analysis by Bloomberg Government. The new total, released Wednesday, includes efforts to construct and then fix HealthCare.gov after serious technical problems threatened to shutter the site last fall. In all, implementation of the Affordable Care Act has cost more than $73 billion since its enactment in 2010, the analysis found. The figures are significantly higher than estimates by the Department of Health and Human Services (HHS) and the White House. Bloomberg Government uses a proprietary database of federal contracts to come up with its numbers.
