California is one of the few states charging ahead on establishing one of ObamaCare’s health insurance “exchanges.” According to the Los Angeles Times:

California insurance officials have expressed concern about substantial rate hikes for some existing policyholders going into the exchange.

Under a new rating map approved by state lawmakers, the Department of lnsurance estimated that premiums for similar coverage could increase as much as 25% in West Los Angeles, 22% in the Sacramento area and nearly 13% in Orange County.

California officials have floated the idea of legislating lower prices. One way would be to throw West Los Angeles and Orange County into the same risk pools. That might reduce premiums in West L.A., but only by increasing premiums in Orange County. With a few simplifying assumptions, premiums in both West L.A. and the O.C. could rise by 19 percent. An alternative would be to cap premium increases. One state official proposes a cap of 8 percent. But that would just be an implicit form of government rationing. If insurers cannot charge premiums that cover their costs, they will cover fewer services.

If Oklahoma prevails in its lawsuit against the IRS, or if any similar plaintiffs prevail, California will look pretty silly for charging forward with an Exchange. California will have imposed on its employers an unnecessary tax of $2,000 per worker — a tax that California employers can avoid by relocating to states that have not created an Exchange. It will also have unnecessarily exposed 2.6 million California residents to ObamaCare’s individual mandate — i.e., a tax of $2,085 on families of four earning as little as $24,000 per year, which those residents can likewise avoid by relocating to another state.

Watch this space for development.
