The White House is "as sorry as we can be" that a Washington state woman held up as an example of the success of the Affordable Care Act marketplaces appears to be falling through the cracks, press secretary Jay Carney said Tuesday. In mid-October, President Obama cited single mother Jessica Sanford as an exchange success story after she wrote to him after being able to sign up for insurance in early October. She's since learned that her state's system miscalculated her tax credit and that her out-of-pocket costs will be substantially higher than expected.
