Unfortunately, "letting it happen" other than of course many people potentially suffering or dying, it presumably wouldn't have much of an affect on voters, as it would simply be spun that it's somehow the previous Administrations fault, or the other parties fault etc. Thankfully we still have the courts, even as more bias judges get seated.
The Daily Show's Jordan Klepper had a sad clip of a Trump supporter demanding to know where President Obama was during Katrina, and that he should be investigated for his failures.
(The answer, of course, is "he was a state Senator in Illinois at the time".)
I'm on the fence about this kind of talk, to be honest. I ask myself sometimes, is it fair to demean those who have been let down by the state they were educated in? I know that generally Americans are uninspired and under educated, but a lot of that comes from systematic and cultural issues rather than it being a fault of the person itself.
