I believe it to be fair to say all societies rely on some form of trust in others and the institutions setup within to function.
Regardless if it is in a Democracy, Republic, Monarchy, etc.
Regardless of it's means of resource distribution such as capitalism, communism, socialism, etc.
America for example, despite at times in the past having slavery being legal, committing genocide, segregation, the stealing of land, etc.
Despite being majority one religion.
Still expanded the vote. Expanded freedoms. Expanded access to education. And has shown an ability to let people that were previously expected to hide to live out in the open and freely.
If we are going to really take one survey result at one moment in time as gospel to say that American voters can't be trusted seems counter to the examples of the past where despite majority of Americans voters feeling one way, opinions were changed and progress was made. Slowly. Painfully. Yet still some positive direction.
Thanks for reading my rant and I'll leave with one last thing:
The public trust is sadly a fragile thing. When that trust is abused and poisoned by the very elected officials that have sworn to protect it the voters faith in the system becomes erroded. It unfortunately then takes longer and more work to rebuild that trust again. To move back to a society where arguments were made in good faith; not to just to troll or wage culture wars.
