She has a voice. Look at Michelle Obama and her work to give kids healthier meal choices at school, plus her whole dancing workout thing. My guess is that Sander's pig wife would try to spread a message of acceptance and love for fat women/young girls. If you watched her response about the Clinton bashing that went on national TV today, there's something about her demeanor that screams SJW.  Fat fashion would also get a place in the spotlight since US fashion is always critiquing how the First Lady dresses.
