First Lady Michelle Obama stopped by "The Daily Show" Tuesday night, not only to promote her new book on gardening and eating right, but to chat candidly with Jon Stewart about how her approval rating is higher than President Obama. "You have an approval rating that's like 85-90%," Stewart told the First Lady. "You're ice cream!" "I'm vegetables," Mrs. Obama corrected.
