Under California law the Lt. Governor replaces the recalled Governor.
While Davis is a predictable failure he represents much less of a potential threat to California's culture than does Bustamante.
Bustamante has a political history that is aligned with Mexican separatism.
For the record Bustamante has publically stated he is a "first generation" Californian (US citizen) but proof that he was born in the US has never been made public.
It's apparent that Davis has an unexpected insurance policy in the form of Cruz "I didn't mean to say the N-word" Bustamante.
Or maybe not so unexpected...
Under the state Constitution (scroll up a few posts and you'll see it), it appears that the recall election can carry the name of one or more candidates who would be the replacement:
An election to determine whether to recall an officer and, if appropriate, to elect a successor shall be called by the Governor and held not less than 60 days nor more than 80 days from the date of certification of sufficient signatures.So Bustamente wouldn't automatically be the new gov. He'd have to run for it.
