Jeff Anderson argues that ObamaCare has an incurable preexisting condition: It eats away at the private insurance market on which it relies. That market cannot survive ObamaCare’s hubristic mandates, and ObamaCare cannot survive the collapse of that market. On their present course, both are doomed. The challenge for conservatives is to figure out how, upon the law’s repeal, to rescue private insurance. If conservatives don’t save that market, liberals will—only it will no longer be a market for private insurance, and there will no longer be millions of purchasers, but just one.
