I believed it too. Every word.
I believed a movement had finally arrived that would not lie, would not sell out, would not betray the people who trusted it. I defended it at dinner tables, on screens, in family arguments that ended badly. I don't write this from the outside, as someone who was never there. I write it from the inside, as someone who was there and walked out.
I'm not talking about the ones who profit. Those are easy to understand: they do it for money. I'm talking about the teacher, the nurse, the college student, the retiree counting every dollar. I'm talking about honest people who would never take a cent that wasn't theirs, and who still defend, tooth and nail, the ones who do. That is the question that matters. And the answer is not in economics. It's in the mind.
A note before we begin. This essay was first written about Mexico and its ruling party, Morena. But the machine it describes is not Mexican. It is human. So this version speaks to the American reader, and to the loyal partisan on either side who has learned to defend the indefensible. I use the Democratic Party as the example here, not because its failures match Morena's in scale, they do not, but because the psychology of blind loyalty works the same everywhere. Read it, and you will recognize the pattern in your own tribe. That recognition is the whole point.
What can no longer be unseen
Before we get to the mind, let's put facts on the table. Not opinions. Facts, with sources.
In 2024, a sitting United States Senator was convicted on all counts in a federal corruption trial. Robert Menendez, Democrat of New Jersey, was found guilty of taking bribes, including cash and gold bars, in exchange for his official power, and of acting as a foreign agent for Egypt. He was sentenced to eleven years in prison. He is only the seventh sitting U.S. senator ever convicted of a federal crime. He maintained his innocence and is appealing.
The same year, a sitting Democratic congressman, Henry Cuellar of Texas, was indicted along with his wife on charges of bribery, money laundering, and acting as foreign agents, accused of taking roughly $600,000 from a foreign oil company and a bank. He pleaded not guilty. He is entitled to the presumption of innocence, and his case has not been decided.
What the files say
Sources: U.S. District Court, Southern District of New York (Menendez conviction and sentencing, 2024–2026); Department of Justice indictment of Rep. Henry Cuellar (2024). Cuellar is presumed innocent; his case is pending.
And here is the part that is hard to explain: when Menendez was convicted, his own party's leadership called for him to resign. But out in the country, among loyal voters, the reflex for many was not to face the facts. It was to minimize, to whatabout, to say "both sides do it," to change the subject. That reflex is not stupidity. It is the mind protecting itself. That is what this essay is about.
I am not asking you to trust me. I'm asking you to read the court record. A federal conviction. A federal indictment. Sworn testimony. And still, millions keep defending, deflecting, looking away. That is the question. Let's go to the mind.
The hunger that also thinks
I have to confess where I started, because hiding it would be dishonest. My first suspicion was harsh, almost brutal. For a moment I thought this had to be something mental, something broken from birth, something that can't be fixed. The thought crossed my mind and I didn't like it, but I had it. And then I forced myself to do exactly what I'm asking the reader to do in this essay: to doubt my own conclusion and look for evidence before stating it.
The evidence took me somewhere else, and somewhere worse. There is no gene for how you vote. No political preference is inherited in the blood, and anyone who claims it is, including me, had I stayed with my first suspicion, would be telling a lie that also insults. If the believer were lost from birth, so was I, and I could never have opened my eyes. My own change of mind is proof that no one is condemned by their biology. So I corrected my conclusion. And in doing so I found something worse than a personal defect: I found a design.
The science is clear, and I didn't invent it. The prefrontal cortex, the part of the brain that plans, controls impulses, and makes decisions, depends on specific nutrients to function: protein, iron, iodine, zinc. Without them, the formation of connections and the regulation of neurotransmitters like dopamine are impaired. A brain fed on cheap refined carbohydrates, on ultra-processed food engineered for shelf life instead of nutrition, is a brain whose deciding muscle has been quietly weakened.
The fuel the mind is missing
Sources: NHANES / peer-reviewed nutrition research on ultra-processed food and cognition; USDA and published SNAP analyses. SNAP participants consume disproportionately high levels of ultra-processed food, linked to worse cardiometabolic and cognitive outcomes.
Look at the machine as a whole. A political class lets whole communities live on cheap, subsidized, ultra-processed calories, underfunds the schools and clinics that might lift them out, and then arrives every cycle with a check and a promise. First it starves the plate. Then it hands out the crumb. And a brain running on sugar and starch, exhausted and inflamed, is a brain that clings harder to the tribe and fears change more. This is not the voter's fault. It is the predictable result of a policy, not a defect of their nature.
Let me be clear, because no one is being insulted here: the person who still believes is not inferior and not lost. They are the primary victim of this scheme, not its accomplice. And if I, who ate well and could read and compare, took years to open my eyes, how can we demand instant clarity from someone deciding on an empty stomach and an underfueled brain? Compassion is not weakness. It is the only honest place to begin.
What happens in the mind
Let me be clear about something first, out of respect. This is not a genetic problem. There is no gene for party loyalty, no birth defect, no mental inferiority. The truth is more uncomfortable: what the loyal partisan's mind does is exactly what your mind, my mind, anyone's mind would do. They are not broken. They are running the standard human operating system, exploited with precision.
Here are five mechanisms, in plain words. And note: researchers find these biases operate on left and right alike. This is not about one party being dumber. It's about being human.
How the mind defends the indefensible
Dissonance
When the truth hurts, the mind changes the truth. Accepting you were deceived means accepting you were wrong for years. That hurts like a betrayal. Deciding "it's a smear, it's the other side" doesn't hurt. The mind reaches for the painkiller. Psychologists call it cognitive dissonance.
Sunk cost
The more you've given, the harder it is to let go. It's what traps the gambler chasing losses. The loyal voter isn't defending the party. They're defending years of their own emotional investment.
The tribe
Humans didn't evolve to be right. We evolved to belong. First we pick a side, then we arrange the facts to prove our side was right. Nobody accepts a fact that would force them to betray their tribe. It's called motivated reasoning, and we all do it.
System justification
People are driven to defend the status quo they're part of, even when it works against their own interest, because it's their status quo. A documented bias, not an accusation. Letting go of the party means letting go of a piece of your own identity.
"They give me something"
The last trap: "Sure, they're flawed, but they deliver for people like me. The others gave me nothing." It isn't foolish. It's the logic of someone the system left behind, now getting a little back. The benefit doesn't buy the vote. It buys silence about the rot.
Put the five together. Dissonance that numbs. Investment you won't abandon. Tribe over truth. Identity over evidence. And a small benefit that buys silence.
Why "they help me" beats "they take from us"
The brain doesn't compare amounts. It compares the near against the abstract. And the near always wins.
A benefit that arrives works not because it buys the vote, but because it makes the corruption abstract. No one gets outraged over a figure they can't see when a deposit actually lands.
The illusion of the alternative
Here's the part that stings the other side. While the loyal voter's mind runs all of this, the opposition believes it will win by knocking on doors and going door to door. Let me state my thesis plainly, for you to weigh:
Think it through with what we've just seen. If the voter stays out of loyalty, out of tribe, out of the check that arrives, what does the opposition offer? It asks them to return to the people who looked down on them. It asks them to betray their tribe. It speaks to the part of the mind that judges by law and evidence, while the decision is being made by the part that judges by loyalty and by the stomach. It's talking to the wrong organ. That's why it loses. Not because it doesn't knock on doors. It loses because when the door opens, it has nothing different to offer.
Only a citizen can free a citizen
Not the opposition, which asks people to betray their tribe. Not the facts, which speak to the part of the mind that doesn't decide. Not online outrage, which only hardens the trenches.
Only the neighbor who talks to the neighbor without contempt. Only the one who belonged, and opened their eyes, and doesn't judge the one who hasn't yet. That voice, equal to equal, reaches where no politician can. Conversion isn't preached from above. It spreads from beside.
The only way to break the spell is not to shout at the voter that they're wrong. It's to finally offer what the party promised and failed to deliver: a real fight against corruption and impunity, with immediate, visible results. Not in a speech. On their street. In their clinic. In their paycheck. Real, verifiable opportunity, not a check that keeps them dependent and a plate that keeps them hungry.
It won't be the parties. It will be us. And there isn't much time. I believed it too. That's how I know you can stop believing. And that's how I know only we, equal to equal, can help others wake up.
The hostage doesn't wake up because you shout at them. They wake up when another hostage, already free, shows them the open door.
