But Puerto Rico's problems stand out.
The president has been busy campaigning in Alabama and arguing with the NFL and chastising his Health and Human Services guy Price for spending hundreds of thousands of dollars on flights for business as well as personal travel. Obviously, the president has little time for Puerto Rico. Maybe because Puerto Rico speaks Spanish? Or maybe because a Trump golf course in Puerto Rico went bankrupt? Or maybe because he thinks Puerto Rico's a foreign country?
While he dithered, Puerto Rico suffered. I won't show a lot of pix on the misery people there are enduring, but I did steal this photo and caption from the AP (couldn't resist the cat):

Things aren't much better today but I believe a nudge from Hillary Clinton steered the president in the right direction. He finally sent the hospital ship Comfort there and put in a three star general to oversee operations and waived temporarily the Jones Act that kept any but US ships from transporting goods to the little island. (A lot of US shippers stood to lose money; the fact that the devastated Puerto Rico would pay twice as much to get supplies didn't bother the shippers. Or the president either, evidently.)
If you want to donate to relief efforts, here is a page from the NY Times that lists charities and rates them. The first four seem to be the best buy for your buck.
Also, the Salvation Army is an old dependable, with a large percentage of its donations going to the intended recipients. Not only are they helping Puerto Rico, they are also there for the other islands hard hit by Maria.
And there is always the Red Cross. It's not one of my favorite charities, but it's been around a long time. Be sure to choose "Hurricane Maria" to direct your donation.
Let's all be thankful for what we have.
