"That government is best which governs least" is one of the most durable pieces of boilerplate in the chop shop of American political cliches. It has been variously attributed to Thomas Jefferson and Thomas Paine, but was actually used by Henry David Thoureau in "On Civil Disobedience." And Thoreau himself apparently stole it. According to one web source the line "first saw print in 1837, in the editor's introduction to the first issue of United States Magazine and Democratic Review." <http://72.14.203.104/search?q=cache:r4YhPE6TtoMJ:www.geocities.com/peterroberts.geo/Relig-Politics/TJefferson.html+government+is+best+governs+least&hl=en&gl=us&ct=clnk&cd=8>
The White House press corps may not have any well thumbed copies of "On Civil Disobediance" at hand or any back issues of United States Magazine and Democratic Review lying around, but I would have to think they recognized the joke.
