Copy-editing the primaries: In the wake of John Edwards's departure from the Democratic race, Obama and Clinton both released sucking-up statements aimed at securing an endorsement from the cheery populist.

Talking Points Memo
, Real Clear Politics, and Politico all include this sentence in Obama's statement: "John and Elizabeth Edwards have always believed deeply that we can change this -- that two Americans can become one, and that our country can rally around this common purpose." (Emphasis added.)

Of course, Obama meant to say that two Americas can become one -- an attempt to connect Edwards's "two Americas" theme with Obama's own message of unity. (Indeed, that's how Obama's website has it.) But someone -- a sleep-deprived Obama staffer, perhaps? -- added an extra n, and now it looks as though Obama was paying some kind of weird tribute to the Edwardses' marriage.
