The other half are things which are ultimately beyond his control or due to a biased media. Did he really "fail to push" the power crisis or did the media just not pay attention to his "pushing", or even try to defuse it and rush to Gray's defense? If half of Californians are so partisan Dem that they're gonna pull the lever for Gray no matter what, then what good is "pushing the power crisis"?
I guess I just have a hard time blaming Simon for the fact that a large proportion of Californians are knee-jerk partisan Democrats. That's not his fault. He didn't win because a large number of voters don't want a Republican governor under any circumstances. If that makes him a "bad candidate" then the only "good" Republican governor candidates in California will have to be Democrats. Maybe Jerry Brown could run? :-)
