Who would want Greyout running anything that might affect his or her wellbeing one way or another?
Simon is a successful businessman and lawyer, to the extent that one needs credentials to run state government.
California may have the fifth largest economy in the world but, like most places, that economy is actually run by the private sector and not by whatever happens to be elected governor. Simon seems unusually well qualified to run the givernment's minority sector of that economy and to reduce it appropriately in favor of balanced budgets, private sector job-creating businesses and lower taxes that will attract the necessary capital to restore California's economy. In short, Simon will know how to keep out of the way. Greyout will not.
