I didn't watch the last 4 minutes yet (debate was about to start and we were watching from the DVR) - so maybe they said something else at the end.... but my understanding about the c-sction was that they wanted to be ready IN CASE...
I find having a weekly schedule of meals helps - it's pretty loose - pasta one day, mexican one day, meat one day, breakfast for dinner, etc - it helps though and lets me still be flexible
