Republicans are chiefly to blame for "natural" disasters in the US. Directly so because they corrupt FEMA, so that the physical events cause a much bigger human disaster.

When the physical event is extreme weather, Republicans are also responsible indirectly because they have forced global heating faster.

Democratic officials do a good job with FEMA. Against global heating, plutocratist mainstream Democrats are not as bad as Republicans, but not good enough to avoid global disaster.
