On Sunday night, I quoted John Dickerson in Slate. “Democratic strategists have long argued that the best way to ensure turnout of the black vote is to suggest the opponent is trying to suppress their participation.” A revealing admission, I thought.

An alert reader informed me that the quote has been altered. Here’s how it reads now. “Democratic strategists have long argued that there’s no better way to ensure turnout of the black vote than if there’s a hint that someone is trying to suppress their participation.” There’s no acknowledgment on the page that the text has been changed.
