A week ago, President Obama began poking his rival, Mitt Romney, with a new term: “Romnesia.” A press release from his campaign helpfully offered the pronunciation and definition:

“Romnesia [Rom-nee-zhuh] Noun—a condition affecting Mitt Romney, who has shifted his positions from ‘severely conservative’ to ‘severely kidding’—conveniently forgetting the conservative promises he’s made over the past six years that he’s been running for president.”

In a campaign speech yesterday morning in Ybor City, Florida, Obama elaborated on the ailment. Romnesia means “you can’t remember what you just said last week,” the president explained, and a symptom is “a sudden fuzziness about what’s on your website.” But “this is a curable condition,” the president added, to great laughter, “and Obamacare covers preexisting conditions.”
