“The trouble with political jokes is that they get elected to office”

“The trouble with political jokes is that they get elected to office” is a quote frequently attributed to Henry Cate VII, but he appears simply to be a 1990s contributor to rec.humor. The phrase is cited from 1958 and is attributed there by nightlife columnist Earl Wilson to actor Tony Pettito.
 
Former New York State Governor Eliot Spitzer—who resigned in disgrace after it was revealed that he visited with prostitutes—had this statement in his 1977 Horace Mann High School yearbook: ““The worst thing about political jokes is that some of them get elected.”
