Is it incompetence? Or are they intentionally letting Republican voters die?

Illegal immigrants - Let's give them free food, free housing, free whatever they want.

Hurricane Flooding - Oh what are we going to do? We can't be expected to help out every person in need!

This is a standard tool in the evil playbook. Feign incompetence when you're doing something evil on purpose. If it's just incompetent hurricane response, too bad, maybe they'll learn and do better next time. If they're intentionally ignoring hurricane victims because they spent all their money and resources on illegals, now there are tough questions that are going to be asked.

Always pretend to be incompetent so you don't get called out for being evil.

There's also private charities that are running circles around the government. Allegedly they're being blocked from delivering aid on their own.
