The Republican response to the State of the Union was delivered by Cathy McMorris Rodgers, Republican representative from Washington — and it was remarkable for its lack of content. A bit of uplifting personal biography, a check list of good things her party wants to happen with no hint of how it plans to make them happen.

The closest she came to substance was when she described a constituent, “Bette in Spokane,” who supposedly faced a $700-a-month premium hike after her policy was canceled. “This law is not working,” intoned Ms. McMorris Rodgers. And right there we see a perfect illustration of just how Republicans are trying to deceive voters — and are, in the process, deceiving themselves.

I’ll get back to “Bette in Spokane” in a minute, but first, is Obamacare “not working”?

Everyone knows about the disastrous rollout, but that was months ago. Since then, health reform has been steadily making up lost ground. At this point enrollments in the health exchanges are only about a million below Congressional Budget Office projections, and rising faster than projected. So a best guess is that by the time 2014 enrollment closes on March 31, there will be more than six million Americans signed up through the exchanges, versus seven million projected. Sign-ups might even meet the projection.

But isn’t Obamacare in a “death spiral,” in which only the old and sick are signing up, so that premiums will soon soar? Not according to the people who should know — the insurance companies. True, one company, Humana, says that the risk pool is worse than it expected. But others, including WellPoint and Aetna, are optimistic (which isn’t a contradiction: different companies could be having different experiences). And the Kaiser Family Foundation, which has run the numbers, finds that even a bad risk pool would have only a minor effect on premiums.
