I am reliably informed by people with some insight into Missouri government that Parson is exceptionally terrible. Incompetent or malicious, depending on the day.
I gather the previous (also Republican) governor, Greitens, who may or may not have been into some weird/illegal sex stuff and was forced out over it, was actually pretty good. Seemed to truly care about governing well and improving the functions of state government, at least, which Parson does not.
