The cost of being uninsured in America is going up significantly next year for millions of people.

President Barack Obama’s push to cover America’s uninsured faces another big test Monday. This time, it’s not only how the website functions, but how well the program itself works for millions who are starting to count on it.

HealthCare.gov is working better, but immigrants are running into what looks like an obvious slip-up.

As a crucial second sign-up season gears up, the Obama administration said Sunday that HealthCare.gov is stable and working well, a far cry from last year’s frozen computer screens and frustrated customers.

The fear is that entrenched political opposition and renewed legal challenges may yet collapse the program that’s bringing health care to millions of previously uninsured Americans. The administration can’t afford another technology meltdown.
