Sure, the legislators and the governor run the government, but, who elected the idiots in the first place? California voters brought all those problems upon themselves.
I suspect that California's elections are similar to those at a national level - the choices of candidates dwindles to 2 or 3 drones, both from the left, the only difference being one has a "D" next to his name and the other, an "R". In these situations, it's impossible to NOT choose a poor candidate.
To put it in perspective, look at our national Presidential election last November - we ultimately ended up with a choice between a socialist with no economic sense and a marxist/fascist with a desire to destroy the country. The marxist won, but given the previous behavior of the socialist, that selection would have proven problematic as well.
When only idiots are running for office, one would expect that only idiots will win elections.
