In Week One, Obamacare health insurance exchanges have been so swamped with traffic that they have been groaning under the strain. That could be a good sign for a law that America supposedly hated — if the Obama administration can get the federal website bugs worked out before those potential customers get scared away. "I've been trying nonstop. It's not working. We can get to the third screen, and then it dies," John Foley of the Legal Aid Society of Palm Beach County, one of the "navigator" groups that's trying to sign up uninsured people in Florida, told POLITICO on Thursday. He said the group has put off all enrollment and told customers to come back next week.
