I get the urge to find someone to blame. It's not the fault of the voter, because that would imply personal accountability. Or at the very least, it would imply a lot about the underlying character of chunk of the population.
On the other hand, you can't blame the media for gas price reports. Or the cost of housing. Or the people dying of measles. Or the men in masks rounding up people. The voter can see all that themselves.
The voter knows about the current conflict with Iran. That is not a "media bias". They are free to decide themselves if that is justified.
The voter who spends all day on Fox news is welcome to decide for themselves if they want a hand-out of cash promised for after the the election. (A promise they've heard before, but not seen).
So yeah, it eould be nice to blame the oligarchs, or the media, or China, or the church, or pretty much anyone, as long as that anyone is not the voter who can see what is happening, and votes for more of the same.
But a third of Americans approve of the current administration. Around half of the people who voted, voted for this administration. And a lot of the footguns you refer to were gleefully part of the campaign.
If you want to apportion blame you might include moderate voters who may not approve of the status quo, but alas are so partisan that they cannot vote for the other side.
With more elections imminent, it remains to be seen if it's really the oligarchs fault, or if the root fault is the real source of power.
