Conservatives used to say Obamacare is socialized medicine. Now they say it is a “government bailout” of insurers.

The new claim is just as misleading and cynical as the old one.

The latest conservative plaything is a pair of previously obscure Obamacare features: “reinsurance” and “risk corridors.” Their mechanisms are a bit complicated to explain. (Read here if you want the details.) What matters is their shared purpose, which is to reimburse insurance companies that end up taking heavy losses—say, because the new marketplaces don’t attract enough young, healthy subscribers. Remember, insurers depend on premiums from people in good health to subsidize the costs of the sick. Without the right mix, the premiums insurers collect won’t be sufficient to cover the cost of clams. They’ll lose money, raise premiums in the future, drop out of the market altogether, or some combination of the three. In short, bad stuff will happen.

To Obamacare supporters, reinsurance and risk corridors are tools for stabilizing the insurance market and easing the transition from the old system to the new. (That’s why I’ve been calling them “shock absorbers.”) But the provisions started attracting scrutiny from the right in the fall, when policy watchers like David Freddoso of Conservative Intelligence Briefing first wrote about it. Now reinsurance and risk corridors are getting more sustained attention from the Weekly Standard, Fox News, and the conservative movement writ large. Republican Senator Marco Rubio has sponsored a bill to repeal the risk corridors. “Why should taxpayers have to bail out health insurance companies in the increasingly likely event that ObamaCare leaves them with financial losses?” Rubio wrote this week, in an op-ed for the Fox website. “This is government favoritism and corporate cronyism at its worst, and it’s taxpayers that will pay the price unless we stop it.” Insurers are sufficiently spooked that, as Buzzfeed’s Kate Nocera has reported, they are undertaking a lobbying campaign to keep the provisions in place.

The bailout analogy is potent. And it’s certainly accurate to say that, under Obamacare, some insurers may collect payments from the government to help offset losses. But the analogy breaks down after that.
