President Barack Obama has apologized for repeatedly assuring Americans that if they liked their health insurance plans they could keep them under the Patient Protection and Affordable Care Act. Now the Obama administration has delivered another bogus assurance.

On Monday in Orlando, Health and Human Services Secretary Kathleen Sebelius told reporters: "There is absolutely no evidence - and every economist will tell you this - that there is any job loss related to the Affordable Care Act. I know that's a popular myth that continues to be repeated, but it just is not accurate."

Actually, that "myth" was given fresh credence early this month when the Congressional Budget Office forecast a reduction of more than 2 million in the U.S. labor force, largely due to Obamacare.

The health reform law's defenders responded that a decline in the number of people in the work force isn't the same as a loss of jobs.

Yet that narrow semantics dodge (it depends on what the meaning of the term "job loss" is?) doesn't alter the logic of this CBO prediction: Many currently working Americans will choose to leave the labor force because the Affordable Care Act will provide medical insurance for them. Many jobless Americans will choose to stay that way for the same reason.

OK, so obtaining health insurance without the requirement of a job does sound liberating.

However, at a time when the percentage of Americans in the labor force is at an historic low, reducing its ranks while adding another expensive federal entitlement is a sure recipe for pushing the record $17.3 trillion national debt ever higher.

And in the wake of last week's "clean" (no spending-cut strings attached) congressional agreement to raise the debt ceiling, our nation needs more - not fewer - taxpaying workers.

Meanwhile, many employers remain wary about which Obamacare mandates will take effect and when. Such uncertainty inevitably stifles hiring.

That guessing game persists, even as the president keeps postponing assorted Obamacare mandates, including the requirement that businesses with 50 or more employees provide health insurance to them.

Those executive orders don't just raise serious constitutional concerns in the public sector. They feed confusion - and reluctance to expand - in the private sector.

The Associated Press did report "a glimmer of success" for Obamacare this week from updated statistics showing that "Americans ages 55 to 64 make up 31 percent of new enrollees" in the law's insurance exchanges. For many people who lost their jobs less than a decade from retirement age, that is a timely relief.

Still, somebody has to pay for it. As that story also reported: "Signing up younger, healthier enrollees is seen as more difficult, but crucial to keeping future insurance rates from increasing."

And the numbers of "younger, healthier" enrollees are falling far short of the administration's projections.

The White House long ago lost its credibility on this law.

So just add Secretary Sebelius' "absolutely no evidence" of "any job loss" claim to the administration's ever-lengthening list of Obamacare stretchers.
