Love it so far!

I can't find it right now, but I seem to remember in one of the Sidney stories from the period during her campaign (maybe the one with the custom doll?), there was a line indicating that Sidney had been required to wear at least a bikini in her early TV interviews, but later on she was allowed to go on TV outfitted in "full Sidney" mode. If I'm remembering that correctly, it seems highly probable that Jennifer would eventually realize that Sidney also helped to normalize public nudity for young girls, which would certainly count as a significant change to the world.

Perhaps this would be an insight most easily gained by talking with someone who remembers those days, aka Nana?
