Advocates for children’s health started worrying months ago that congressional incompetence would jeopardize the nation’s one indisputable healthcare success — the Children’s Health Insurance Program, which has reduced the uninsured rate among kids to 5% from 14% over the two decades of its existence.

Their fears turned out to be true. Funding for CHIP runs out on Saturday, and no vote on reestablishing the program’s $15-billion appropriation is expected for at least a week, probably longer. That’s the case even though CHIP is one of the few federal programs that has enjoyed unalloyed bipartisan support since its inception in 1997. The consequences will be dire in many states, which will have to curtail or even shut down their children’s health programs until funding is restored. Hanging in the balance is care for 9 million children and pregnant women in low-income households.
