As Desi would say to Lucy, "you got some 'splainin' to do." I agree, here goes. The districting structure of CA is so gerrymandered that it is extremely unlikely to elect a Republican majority at any time in the foreseeable future. Whoever is governor will work with a Democratic majority.
A Dem majority will be inclined to "blow off" a GOP governor, less likely to do so for one of their own party. Like it or not, a Dem governor will have a better chance of working out a solution to California's structural problems than one from the GOP. CA needs a solution, as what they've got now doesn't work.
BTW, the above reasoning does not apply to who CA elects for senator. I hope they go for Fiorina.
