As insurers begin releasing details of next year’s insurance premiums, Republicans should reach out to and appear with families getting hit by bigger bills. Mr. Obama promised premiums would go down by $2,500 per family, as did most of the Senate Democrats running for re-election this fall.

Yet many families have already seen significant price increases and will continue to see them. Recent analysis from the think tank America Next revealed that between 2010 and 2013 individuals suffered $6,039 and families $17,344 in higher premium costs because of ObamaCare’s failure to cut them as promised.

This is in part because an estimated 27% of people who enrolled in ObamaCare have serious health challenges and draw on their coverage substantially more than the national average. This ObamaCare subset is roughly twice as large as the comparable group left with private insurance in the individual market.
