Newsom is just a Frisco creature.
He would never carry San Diego
He had that scandal with the married staffer awhile back. Where there’s smoke, there’s fire. There are also rumors about him at wild parties and some unsavory stuff. Drug use would not surprise me. He’s very ambitious so I can only surmise there’s a dirty jacket on him that he figures might even ruin the gig he’s already got so he’s backing out.
Just a guess.
