Lots of folks occasionally forget where they put their car keys. But who forgets telling a national television audience that the Patient Protection and Affordable Care Act would reduce their health insurance expenses?

Seemingly, House Minority Leader Nancy Pelosi.

Last summer on NBC’s “Meet the Press,” Rep. Pelosi said that under the health reform law, “everybody will have lower rates, better quality care and better access.”

However, last week at a news conference in Washington, the California Democrat said: “I don’t remember saying that everybody in the country would have a lower premium.”

Has she also forgotten similar assurances frequently delivered by President Barack Obama?

He put it this way while unveiling his sweeping health care overhaul as a presidential candidate in 2007: “If you already have health insurance, the only thing that will change for you under this plan is the amount of money you will spend on premiums. That will be less.”

Actually, it’s becoming increasingly obvious that private insurance premiums will be significantly higher under Obamacare.

Yet President Obama, while trying to sell the public on the bill, repeatedly stressed that Americans who liked their plans could keep them as they were.

Despite conservative warnings that his pledge would be unsustainable after Obamacare’s massive intrusion into the medical marketplace, the president pushed that 2,700-pluspage bill through Congress without a single Republican vote in 2010. That was back when Rep. Pelosi was still House speaker.

Keep the revealing gap between Obamacare’s promise and its reality in mind when assessing the tough-but-correct decision by Gov. Nikki Haley and the General Assembly to reject the law’s offer of a vast Medicaid expansion in South Carolina.

At least Rep. Pelosi eventually acknowledged at last week’s news conference that some insurance rates will rise under Obamacare. Still, she tried to soften the blow with this weak pitch: “The fact is the value of what you get for the cost that you pay is a reduction in cost to you.”

Rep. Pelosi was right in 2010, though, when she said of the legislative behemoth: “We have to pass the bill so you can find out what is in it.”

And Americans are only starting to find out how high the Affordable Care Act’s unaffordable bill will be.
