George W. Bush hurt his presidency by his inadequate response to the disaster caused by Hurricane Katrina in New Orleans. Now it looks like Donald Trump is creating the same kind of problem for himself with his slow and grossly inadequate response to the disaster in Puerto Rico caused by Hurricane Maria.
A majority of Americans believe the federal response to Puerto Rico has been too slow, and they don't believe the federal government is doing enough to help Puerto Rico. Trump is already the most unpopular of our modern presidents, and his lame response to the Puerto Rican disaster is not going to help that. It may well make him even more unpopular.
