Theory from SpouseAnon: the CA fires were set to disperse the Dem voters to other red states to turn them blue.
If you've ever had anything significant happen to your home, insurance doesn't cover everything, and rebuilding is difficult. What do you do? One option is to move to other states.
As an asylum state, CA will welcome illegals who generally vote Dem and who will populate the state after the present citizens vacate to cheaper states that are Republican.
So many fires, so large in scope, in so many places - the odds they are organic in nature starts to slim significantly.
Just a theory, but plausible.
