The number of official candidates for the 2016 Republican Presidential nomination has risen to thirteen, according to officials at the Centers for Disease Control. The count had stood at twelve since the announcement last week by the reality-show host Donald Trump, leading many at the C.D.C. to privately hope that the epidemic was losing steam. But with the entry of Louisiana Gov. Bobby Jindal into the race on Wednesday, the C.D.C. was forced to hold a press conference to announce the worrisome news that the number of candidates had increased yet again. It might have been misplaced optimism on our part, but we had started to believe that this thing had been contained, said the C.D.C. spokesman Dr. Harland Dorrinson. Regrettably, it has not. While scientists disagree about how running for President spreads from person to person, most epidemiologists believe that a candidacy needs an environment rich in narcissism and delusionplus a host to feed on, ideally a sociopathic billionaire. The C.D.C. spokesman refused to address speculation that Wisconsin Gov. Scott Walker would soon enter the race, bringing the number of candidates to fourteen. I dont want to say anything that might cause the public to panic, he said. Watch: An episode of Mary Norriss Comma Queen about the distinction between who and whom.
