Ed mentioned this in an update, but the video is worth a watch. Jake Tapper asks if Obama’s three references to Seamus are part of the “important policy debate” the White House is trying to have, which is allegedly being foiled by Romney and Ryan.

Tapper calls the comment “cable catnip” the White House should be savvy enough to avoid. Carney exhibits wide-eyed innocence as most of the press corps chuckles.
