It will be newsome. A checkmark on his way to the White House.
Are you crazy? Newsom is the governor, why would he want to become Senator? Governor is a better platform for president. In fact, I would say if he appointed himself Senator, it would be a sign he is not running for president.
Voters hate this, by the way. Of the none governors who has themselves appointed Senator, only one was reelected.
Newsom can’t nominate himself.
