She says in the video that she thinks a law requiring Americans to eat vegetables would be stupid. Looking at pictures of her I suspect she wouldn't think a law requiring Americans to eat donuts would be stupid.
The question that matters and that nobody has asked (at least I haven't heard about it) is this:
Which of the following do you agree with:The answer to that question would be more useful than any of the questions I've heard asked in the hearings.

From what I've read and heard so far I think it is pretty clear what her answer would be.
