The Clinton campaign has been using Chelsea as a surrogate since the final few weeks in Iowa, even though the response to her has been lukewarm at best. They've now flown her to New Hampshire and elsewhere, where she's taking rallies to promote her mother as "Grandma-in-Chief."
Only, yesterday's speech went a little awry. While at a campaign stop in Minnesota (a must-win for the Clinton camp), Chelsea made a Freudian slip, referring to "Bernie Sanders" as "President Sanders."
Obviously, she didn't mean to suggest that her allegiances are split, but it's pretty funny nonetheless. The Clinton campaign is losing steam a little, and this can't be great for internal morale.
