Monday is the deadline to sign up for insurance on www.HealthCare.gov.

Or is it?

Confusion persists over which elements of the Patient Protection and Affordable Care Act are going into effect - and when.

For instance, the Obama administration announced on Tuesday night that it would extend that previously "firm" March 31 deadline for two to three weeks.

So is that two or three weeks?

The stated justification for this latest postponement was that some Americans were having difficulty getting signed up. So to get that extension, all you have to do is assert that you are among that group struggling with that technology.

House Speaker John Boehner, R-Ohio, delivered this heated reaction to the new delay Wednesday:

"Last night brought us yet another delay of Obamacare, another deadline made meaningless. As if he [President Obama] hasn't put enough loopholes into the law already, the administration now resorting to an honor system to enforce it. What the hell is this? A joke?"

No, it's not a joke.

And no, the speaker shouldn't use such coarse language.

But it is reasonable to express growing exasperation while questioning how far the administration will go in warping the health care bill it so fervently sought.

The White House did predictably hail Thursday's news that more than 6 million Americans have now signed up for insurance under the online marketplaces set up by the landmark 2010 legislation.

That was a higher figure than some analysts forecast - though still short of the White House's original goal of 7 million goal by this point.

However, serious concerns linger about the failure of enough young, generally healthier Americans to buy policies on those exchanges. If older, generally less healthy Americans keep dominating those sales, the premiums inevitably will have to rise to cover their higher average medical costs.

And if the president keeps issuing constitutionally questionable executive edicts to alter the Affordable Care Act, Democratic federal lawmakers should have more reason than their Republican counterparts to protest. After all, their party passed the bewildering behemoth through both houses of Congress without a single Republican vote - though 34 House Democrats did oppose it.

Meanwhile, though House and Senate Democratic leaders are still backing the president's unilateral changes to Obamacare, many of their party colleagues seeking re-election in the fall are understandably running away from the law as fast as they can.

The Affordable Care Act was supposed to stabilize the nation's health care system with assurances of widespread insurance coverage. Instead, it is injecting large doses of costly uncertainty to individual Americans and businesses.

And that uncertainty is exacerbated each time the White House arbitrarily changes the Obamacare rules.
