But ceaseless advances in government privacy‐​invading technology have made the Nixon‐​era suspensions of individual constitutional liberties appear amateurish.

For an example that far exceeds the once‐​fearsome vision of George Orwell’s 1984, the National Security Agency — with the support of President Obama, who was elected in part for pledging the most transparent administration in American history — is erecting a data tracking center in Bluffdale, Utah, that as of September 2013 will be storing and distributing to other intelligence agencies “all forms of communications, including the contents of private emails, cellphone calls and Google searches, as well as personal data trails — parking receipts, travel itineraries, bookstore purchases.” (Including, I’m sure, e‐​books, to be up to date.) In view of the Obama administration’s strange definition of its transparency, I give you my source: James Bamford, a historian who, more successfully than any investigative reporter, has become familiar with the inner workings of the N.S.A.

It was Senator Frank Church of Idaho who, investigating the state of our privacy in 1975, warned that as the N.S.A. kept evolving without accountability, for Americans “there would be no place to hide.”

Meanwhile, the F.B.I.‘s domestic surveillance powers allow it to open a warrantless “threat assessment” against any American or organization without going to court and without any articulable evidence of imminent or actual criminal behavior.

Turning America into a society under surveillance was never remotely conceived by the Founders, however conflicted they sometimes were. Nor does it seem likely that our resemblance to Iran in this context will be an issue of any consequence in the 2012 elections. The incumbent is, of course, immovable in his definition of national security as it frees him from fealty to the Constitution. Mitt Romney has so far not given any indication that he is in the least troubled by the National Security Agency. And most of the rest of us are concerned with our survival in this perilous economy.

Is this still America?
