The Supreme Court may have declared that the government can order Americans to get health insurance, but that doesn’t mean they’re going to sign up. Nowhere is that more evident than Oklahoma, a conservative state with an independent streak and a disdain for the strong arm of government. The state cannot even get residents to comply with car insurance laws; roughly a quarter of the drivers here lack it, one of the highest rates in the country. When it comes to health insurance, the effort to sign people up isn’t likely to get much help from the state. Antipathy toward President Obama’s signature health-care overhaul runs so deep that when the federal government awarded Oklahoma a large grant to plan for the new law, the governor turned away the money — all $54 million of it.
