As President Obama made another public case for his signature health care law on Thursday, the Department of Health and Human Services released a report touting the affordability of coverage to be offered on the new insurance exchanges scheduled to open on Oct. 1. But the report relies on a price comparison that isn’t particularly relevant.

“Today’s report shows that the Affordable Care Act is working to increase transparency and competition among health insurance plans and drive premiums down,” Health and Human Services Secretary Kathleen Sebelius said in a statement.  “The reforms in the health care law ensure consumers will have access to better coverage at a lower cost in 2014.”
