I have a hard time fathoming why any sane CA'ian would vote for Kammie, though I'm hardly objective. Even pre-Biden her record was one of stupidity, laziness, tyrannous action, and failing to deal with very serious staff problems.
Sadly, name recognition has unwarranted influence, and of the various other names in the OP, her name recognition is far greater than any of the others. I'm not aware that any of those listed other than Porter has expressed interest in running for Governor. I would at least give Dahle and/or Bianco a serious look-over and based on their past, probably could vote for either, in the primary at least.
