A team of medical specialists today revealed that Sarah Palin is suffering from Reagan Disease. The malady is so named because Ronald Reagan was its first famous sufferer.
The disorder is characterized by a relentlessly sunny demeanor, nonsensical stream-of-consciousness jabbering in public forums, and an inability to face inconvenient facts that in extreme circumstances leads to the creation of a parallel reality in which the sufferer takes no responsibility for his or her own actions. The syndrome also causes the dissonant belief in the face of all facts and logic that tax cuts and military aggression are the answer to all problems.
Palin immediately disputed the diagnosis to a crowd of credulous rubes at the Nebraska State Fair. "Those old doctors and their hoity toity degrees-they just want to take me down, doncha know. They aren't real Ameericans like you. Let's hear it for the troops protecting my freedom of speech against these liberal elites! Now who wants a tax cut?" Like the simians they only recently descended from, the crowd hooted and screeched with approval.
Doctors say there is no known cure for the disease and sufferers can cause significant damage to state and country. Common sense on the part of voters is considered the best prophylactic against Reagan Disease but given the electoral history of the past three decades scientist despair that common sense is in short supply.
