Enrollment: ObamaCare loyalists are trumpeting a new Kaiser Family Foundation survey finding that more than half of those who enrolled had been uninsured. But the survey's findings are nothing to cheer about.

First, nobody knows exactly how many ObamaCare enrollees were previously uninsured, because the administration didn't bother to ask for that information when people signed up. So it's been up to pollsters to figure out what happened, and previous surveys showed that only a small percentage of ObamaCare sign-ups came from the ranks of the uninsured.

The new Kaiser survey, in contrast, found that 57% of those getting coverage through an ObamaCare exchange had lacked insurance. But this number isn't nearly as glowing as it first appears.

First, it's bloated. The survey asked whether those signing up had been uninsured at the time they enrolled. Turns out almost 1-in-10 of those listed as "uninsured" had, in fact, lacked coverage for less than three months — presumably thanks to ObamaCare itself. And nearly a quarter had been uninsured for less than a year.

Also, 29% of those uninsured said they would have gotten insurance anyway, even without ObamaCare. The number also doesn't factor in those who dropped insurance once they got a look at ObamaCare rates.

Even if the Kaiser number is right, it's underwhelming. The Congressional Budget Office forecast 6 million would gain insurance through the exchanges this year. The Kaiser survey suggests it's more like 4 million.

And remember how Obama promised that everyone would love ObamaCare because the benefits were so wonderful? Turns out that's not true, either.

The Kaiser survey found those forced to switch plans have far more negative views of ObamaCare than the general public — with 53% expressing an unfavorable view vs. 46% of the public overall. And 57% of those who had their coverage canceled because of ObamaCare say they've been negatively affected by the law.

No wonder, since more than half ended up paying the same or more for ObamaCare plans than what they had, though they often came with higher deductibles, less coverage, fewer choices of doctors, and offered no better financial protection.

The Kaiser survey also found that nearly half of those getting government subsidies through the exchanges don't even know they're on the government dole. An official HHS report says 87% of those enrolled in the federal exchange are getting government subsidies to hold down the cost of ObamaCare coverage, but only 46% told Kaiser they were. Even so, 43% of those enrolled in ObamaCare-compliant plans say they find paying their premiums "difficult."

Also largely overlooked in all the glowing coverage is that far more people ended up moving from employer-based coverage to the exchanges than the government expected. The CBO figured that in the first year, ObamaCare would have a negligible impact, if any, on those who had been getting coverage through an employer.

But the Kaiser survey found 14% of those enrolled in an ObamaCare exchange had employer or COBRA coverage before. Using the White House's enrollment numbers, that works out to more than 1 million workers.

In the end, the Kaiser survey doesn't change any of the central complaints we have with ObamaCare.

The only reason it looks good is because supporters keep lowering the bar for what constitutes success.
