McClintock = Career politician = Zero Actual Experience
Arnold = A Proven Doer, not another "Know-It-All, But I've Never Done Any of It" politician.
By that logic, you should vote for Warren Buffet, or Ted Turner, or any of the thousand wealthy movie stars in California. Experience is nice (although, I seriously doubt if Arnold's experience lifting wieghts, taking steriods, and making movies has any relevance to governing CA), but ideas and leadership is more important. If Arnold were to actually start expressing some conservative stances, more people would support him. It is strange that he seems wholly unwilling to do that.
