I don't recall any governor who ran on a platform of, "here are all the possible scenarios that could impact anyone in my state and how I would approach them." You vote for a governor because you believe they will make a decision you generally agree with when presented with facts. Your vote says that for the next little while you think this person would represent your interests, no matter what happens. Some governors have mild terms, others have catastrophes they have to navigate.
