If media corporations worked together to convince you that a half decent politician is evil incarnate but the politician that helps corporations extort the people is good, what would it look like?
Like say Politician A is a somewhat decent politician that's little bettor or worse then the ones before, but Politician B wants to take away the general people's rights so that corporations can get richer and richer. Corporations band together to make Politician A look like the spawn of Satan with every thing they ever did put under a microscope and blown out of proportion if not outright fabricated, while everything Politician B does is completely buried and debunked by bribed people who are claimed to be experts in their respective fields.
What would that look like? Like what's an example of a claim and an example of the actual truth behind it?
A bunch of ignorant, gullible fools were led to believe a literal convicted felon and rapist who has openly stated he is anti-worker rights, leading a party with a long history of voting against average Americans was a better option than a successful prosecutor with a doctorate in law, leading a party with a long history of voting in favor of average Americans.
We don't need to imagine a "what if humans are stupid and easily misled" scenario. That is the reality we exist in.
