To work successfully, Obamacare needs people like the guy that signed up last week. He selected a bronze plan through the District of Columbia's exchange. And he's highly unlikely to make a single claim in 2014. The guy? None other than Barack Obama. While the president will pay the plan's premiums himself, he's unlikely to make any claims, since his health care is provided through military doctors. Talk about taking your medicine with a spoonful of sugar.
