State Controller (Open): Perez will win 56-43.
State Treasurer (Open): Chiang wins 57-40.
I only picked those two out because they're the only races where you predicted both candidates. However, in all races in California, there will only be two candidates on the ballot per race. Therefore, each prediction should add up to 100%. Assuming Democrats have at least satisfactory candidates for every race, I doubt Democrats will get under 55% in any statewide office. I think the strongest candidates will end up being Brown and Chiang, though I agree that Harris might have a surprisingly strong result as well.
