If it is about Newsom doing some black magic back room deal to protect SVB because of his deposits, he does not have that kind of pull among Banking Regulators. The extent of his power in Banking Regulation (as any other Governor except maybe Hochul) is pleading to Biden and Zeints about any impact SVB may have at a macro level.
If it's about a trust fund child who was groomed by the Pritzkers and Gettys from SF local politics to Sacramento, newsflash that's all politics as every level. Politics has always been impacted by money and fundraising. Name me a politician and I can point you to their benefactor.
