Barack Obama's intellectual sociopathy — his often breezy and sometimes loutish indifference to truth — should no longer startle. It should, however, influence Mitt Romney's choice of a running mate.

In his 2010 State of the Union address, Obama flagrantly misrepresented the Supreme Court's Citizens United decision, which did not "open the floodgates" for foreign corporations "to spend without limit in our elections" (the law prohibiting foreign money was untouched by Citizens United) and did not reverse "a century of law." Although Obama is not nearly as well educated as many thought, and he thinks, he surely knows he was absurd when he said last Monday, regarding ObamaCare, that it would be "unprecedented" for the Supreme Court to overturn a "passed law."

More important, and particularly pertinent to Romney's choice, was Obama's Tuesday speech comprehensively misrepresenting Rep. Paul Ryan's budget. (For Ryan's refutation of Obama, go to ow.ly/a6hPz.) Remarkably, the 42-year-old congressman is today's agenda-setting Republican. Admirably, Romney has embraced Ryan's approach to altering the ruinous trajectory of the entitlement state and forestalling what that trajectory presages, a "government-centered society" (Romney's phrase in his fine Milwaukee speech Tuesday night).
