I’ve asked Secretary of the Treasury Jack Lew and Secretary of Health and Human Services Kathleen Sebelius to explain the massive jump in costs for premium subsidies. The projected figure for subsidy expenditures has gone from nearly $16 billion in the president’s 2012 budget up to nearly $22 billion in his 2014 budget. Why is the administration expecting these costs to soar? Is it because they are seeing employers dropping coverage, leaving more employees to get ObamaCare insurance through an exchange subsidized with these tax credits? Is it because they expect insurance premiums to soar, driving up the percentage-figure the government must cover with subsidies? Maybe both.
