If you'll examine the photo carefully in context, you'll see that she's NOT holding that baby around or over an awkward pregnant abdomen. Certainly not anything like that April 13th photo that may be staged, which would have been taken the same week. The jacket and scarf are hanging straight down. There's no fullness there.
Thank you kind reader for sending me this. Personally, I do think Palin looks thick through the waist here. But since this photo is new to me, I'm happy to have others see it as well, especially in contrast to the Gusty photo.
