Justice Antonin Scalia was “a little disoriented” and Justice Samuel Alito said “that’s pretty incredible.” Chief Justice John Roberts said: “If we accept your constitutional argument, we’re establishing a precedent that you yourself say would extend to banning the book” — a hypothetical 500-page book containing one sentence that said “vote for” a particular candidate…

McCain-Feingold orders people to shut up when political speech matters most. It bans “electioneering communications” (communications “susceptible of no reasonable interpretation other than as an appeal to vote for or against a specific candidate”) paid for by corporations in the 30 days before primaries and 60 days before general elections. Corporations include not only, or primarily, the likes of GM and GE; corporations also include issue advocacy groups, from the National Rifle Association to the Sierra Club. So, yes, if a book published (as books are) by a corporation contains even a sentence of election-related advocacy, the book could — must — be banned by the federal government, and not just during the McCain-Feingold muzzle period.
