Supporting Campbell is your prerogative, it looks close to a neck and neck race between him and Fiorina.
Personally I want him to lose, but whatever floats your boat.
I don’t vote in CA. I am trying to figure out why Palin is supporting a RINO like Fiorina when Devore polls better against Boxer. And Campbell polls the best against Boxer. If the criterion is winning and electability, then logically Palin should be supporting Campbell since ideology is not important for her.
