Barack Obama and Hillary Clinton want insurers to be forced to accept all enrollees for the same premium—regardless of health condition. The result: health plans will run away from high-cost patients and underprovide to them if they do enroll. By contrast, the Medicare Advantage program pays more for high-cost patients. The result: health plans actively compete for the chronically ill and have enrolled more than a million of them in "special needs" plans. So what does Congress want to do about it? Kill the program, of course (see WSJ article here).
