The term flip-flopping doesn’t do justice to Mr. McCain’s self-contradictory economic pronouncements because that implies there’s some rational, if hypocritical, logic at work. What he serves up instead is plain old incoherence, as if he were compulsively consulting one of those old Magic 8 Balls. In a single 24-hour period in April, Mr. McCain went from saying there’s been “great economic progress” during the Bush presidency to saying “Americans are not better off than they were eight years ago.” He reversed his initial condemnation of mortgage bailouts in just two weeks.

In February Mr. McCain said he would balance the federal budget by the end of his first term even while extending the gargantuan Bush tax cuts. In April he said he’d accomplish this by the end of his second term. In July he’s again saying he’ll do it in his first term. Why not just say he’ll do it on Inauguration Day? It really doesn’t matter since he’s never supplied real numbers that would give this promise even a patina of credibility.

Mr. McCain’s plan for Social Security reform is “along the lines that President Bush proposed.” Or so he said in March. He came out against such “privatization” in June (though his policy descriptions still support it). Last week he indicated he isn’t completely clear on what Social Security does. He called the program’s premise  young taxpayers foot the bill for their elders (including him)  an “absolute disgrace.”

Given that Mr. McCain’s sole private-sector job was a fleeting stint in public relations at his father-in-law’s beer distributorship, he comes by his economic ignorance honestly. But there’s no A team aboard the Straight Talk Express to fill him in. His campaign economist, the former Bush adviser Douglas Holtz-Eakin, could be found in the June 5 issue of American Banker suggesting even at that late date that we still don’t know “the depth of the housing crisis” and proposing that “monitoring is the right thing to do in these circumstances.”

Ms. Fiorina, the ubiquitous new public face of McCain economic policy, adds nothing to the mix beyond her incessant display of corporate jargon, from “trend lines” to “start-ups.” Before she was fired at Hewlett-Packard, its stock had declined 50 percent during her five-plus years in charge. She missed earning projections  by 23 percent in one quarter  much as she now misrepresents both the Obama and McCain records. This month she said Mr. McCain wanted to require insurance plans to cover birth control medications along with Viagra, when in fact he had voted against it.

Ms. Fiorina received a $42 million payout (half in cash) from H.P., according to a shareholders’ subsequent lawsuit. With this inspiring résumé, she now aspires to be Mr. McCain’s running mate. So does the irrepressible Mitt Romney, who actually was a business whiz before serving as Massachusetts’s governor. Beltway wisdom has it that the addition of such a corporate star will remedy Mr. McCain’s fiscal flatulence.
