Tuesday is a big day for the White House. That's when new open in every state, where people can buy the insurance the Affordable Care Act requires next year. They will also see if they qualify for new subsidies to help them afford it. The day will be met by both intense scrutiny and complete cluelessness. Policy wonks will be watching like scientists running lab rats through a maze. Camped on the virtual sidewalk outside the new exchanges, just waiting for the online doors to open, are people like Caroline Pearson, a vice president at Avalere Health, a Washington, D.C., consulting firm.
