Kessler points out that the U.S. Bureau of Labor's data "show that women who do not get married have virtually no wage gap; they earn 96 cents for every dollar a man makes."
Moreover, a 2011 study by the Federal Reserve of St. Louis found the wage gap is much lower when women are compared to men with similar characteristics.
Kessler agrees there "appears to be some sort of wage gap, but adds, "it's a bit rich for the president to repeatedly cite this statistic as an 'embarrassment.'"
Notably, after an earlier online version of his fact check column appeared, Obama dropped any mention of the "77 cents" wage gap in his weekly radio address Saturday.
Another questionable figure Obama boasted about last week was his flat statement that under the Obamacare law, "7.1 million Americans have now signed up for private insurance plans..."
Kessler has deep problems with this claim, too. "Note the phrase 'signed up," he cautions us.
As he and other health care experts have said before about the sign-up numbers, they're not all they're cracked up to be. Signing up is not the same as "paying up" month after month.
The key test for Obamacare will be "how many people actually pay the first month's premium." While no one yet knows what the payment trend will be, Kessler applies an 85 percent payment rate, the same rate that's occurring in California.
"An 85 percent payment rate would translate into about 6 million actually paying premiums," he writes, well below the much ballyhooed White House figure. That's closer to CBO's downwardly revised forecast after it learned that many more people were on the plan for only one month.
There are other statistical misinterpretations sprinkled throughout Obamacare's figures. "When all is said and done, the administration might only just meet the CBO's revised estimate of 6 million people...or even fall short," Kessler says.
Obama made another shaky claim about sign-ups last week, as when he said the new number was "on top of the more than 3 million young adults who have gained insurance under this law by staying on their family's plan..."
It turns out this is a questionable, two-year-old statistic from a government estimate that has not been updated. "The factoid is therefore fairly dubious," says Kessler. The "administration's claims about the under-26 enrollment should be treated with extreme caution."
"Are Obama's latest health-care enrollment figures accurate?" the headline over his column asked its readers.
Clearly his figures are deliberately exaggerated -- or worse -- for political purposes in the belief that no one is going to check these numbers, least of all the network news shows that never question any of Obama's claims.
He's made a practice of playing fast and loose with the facts throughout his presidency, and the base of his party is all too willing to swallow them whole.
In a a 2008 presidential debate, he talked of the death of his mother from cervical cancer, saying she spent "the last months of her life in the hospital arguing with insurance companies because they're saying this may be a preexisting condition and they don't have to pay for her treatment." That story was repeated in his 2012 campaign film.
It was eventually revealed that the dispute wasn't about her health insurance which covered her medical bills.
More recently, the policy falsehoods keep coming and President Pinocchio's nose is growing longer and longer.
