We admit we rolled our eyes mightily yesterday when CNN breathlessly reported Obama was having a do-over on his swearing-in. No doubt the same people who insisted he was ineligible to be president were eagely preparing lawsuits insisting this, too, meant he was illegitimately in office. Gah! Please get over it.
In any case, we thoroughly enjoyed this New York Times bit by the brilliant Steven Pinker, which not only blames the goof on the Chief Justice--but also speculates what really was behind it: a tendency toward hypercorrect grammar.
