Help with Researching State Supreme Court Justices

There are 13!!! 13 State Supreme Court Associate Justices on my ballot (California). Other than researching each one to see what the internet has to serve up, does anyone know of a progressive advisor for this that might have done more homework on these individuals than I will probably be able to do? I don't ever remember seeing so many on a ballot before. The options are just Yes or No, they are not running against each other it seems. Any suggestions welcome!
