When it’s getting up to 92, is the air under the house still cooler?
I’d personally worry that even the smallest A/C unit you can get would be problematic in that small of a space. Might be worth air conditioning the rest of your house and unsealing the door instead.
Tricky to elect younger & more competent when the older generation is so much more practiced at the schmoozing aspect, unfortunately. Not to mention better funded by special interests who trust their predictability.
