Bad move. The ad offended even Sesame Workshop, the PBS-affiliated nonprofit behind the legendary children’s program.

It demanded that Obama “take [it] down.’’

“Sesame Workshop is a nonpartisan, nonprofit organization and we do not endorse candidates or participate in political campaigns,” it said in a statement.

“We have approved no campaign ads, and, as is our general practice, have requested that the ad be taken down.”

Obama campaign spokeswoman Jen Psaki said the request is being reviewed.
