Conservative media — and NPR — entertain the possibility of a Hillary Clinton replacement

A day after Hillary Clinton fell ill at a 9/11 memorial service, prompting her campaign to acknowledge a previously undisclosed pneumonia diagnosis, the far-fetched idea that Democratic officials could move to replace her as the party's presidential nominee is floating around in all the predictable places — and at least one not-so-predictable place.

Breitbart, Newsmax, Infowars, Lifezette and Gateway Pundit are among the conservative news sites suggesting Clinton could be pressured to leave the race because of health concerns. British tabloids are all over the idea, too.

The Drudge Report blared Monday morning that Clinton running mate Tim Kaine is "in the bullpen," like a relief pitcher getting ready to take the ball from a starter who can't go the distance. None of this is surprising — or likely.

Many stories are based on tweets by David Shuster, a former MSNBC anchor. Breitbart referred to Shuster as a "left-wing reporter," as if to say, "You should believe that Clinton might be forced out because even a liberal says so."
