It’s been more than two weeks since its launch, but CNN senior medical correspondent Elizabeth Cohen still can’t manage to sign up for a health exchange through Healthcare.gov. And her frustration is growing. “I’ve been trying since day one to get an account and login on healthcare.gov,” she reports. “I failed again … and again … and again.” At one point she scrambled out of bed up at 3 a.m. to try and enroll during low traffic hours. That failed too. Meanwhile, it’s just more empty promises from the Obama administration: We’ll get it fixed … eventually.
