The previous responder is correct: it's your personal decision. My take on the candidates is this: Meg Whitman has experience as a corporate CEO. She did well at Ebay, not so much at FTD. She has extensive ties to Wall Street and that is where her views come from. Being a small businessman who has been dramatically affected by the shenanigans of wall street I'm a little leery of that viewpoint. She also has a record of not voting in elections - for which she has apologized but one cannot help but question why someone who was so disinterested in politics for so many years is suddenly pursuing the position of governor of California at a time when we are experiencing our worst crises in our history.
Jerry Brown is a politician - which has its pluses and minuses. He knows how to work with the legislature - although it was not as dysfunctional in his previous terms as governor. He does have a track record of frugality, truthfulness and respect for the opinions of voters - even when he doesn't agree with them. Since California is not a corporation Whitman's experience will not be the great value that she claims it to be. I don't trust Whitman - many of her ads are gross exaggerations, taken out of context and just plain not true. Brown is not perfect and I don't know if he can pull us out of this mess but I think of the two, he has a better chance of putting California back on the right track. At least he won't be running for president again and I have my suspicions that positioning herself for a run at the presidency is Whitman's true motivation.
