Upending the system requires effort and planning. Electing a moron is going to produce business-as-usual-with-extra-drama, which is not an improvement over business-as-usual-with-extra-efficiency.
Actual improvement has to come from someone with a knowledge of the mechanisms of government and how they can be subverted. We don’t have time for a fuzzing attack on government — by the time such an attack has any meaningful results we’ll be long dead. We need someone to exploit known vulnerabilities.
