"My biggest concern is staying out of war so I voted for the guy I think is Hitler."

Historical fact: In the distant past, guys like this belonged to a Union, and the union told them how to vote.

The union was led by ruthless people whose power was entirely dependent on the support of the union.

The union leaders kept their people happy by negotiating better prices for their labor, and the happy people did what the leaders said. Their tribe was the union, and the tribe stuck together.

At some point the owner class realized it was easy to redefine what happiness meant for idiots: Lying. A lot. Tricking absolute idiots is easy, so they started whittling away at unions with promises of prosperity a union leader could never fulfil, until we get to today where unions and union membership is lower than it's ever been.

And idiots like that still vote for who their handler tells them to, only their handler now has zero investment in keeping them happy. Lying to them is sufficient as long as the rest of the tribe reinforces the lies. The tribe is now everyone too stupid to not vote for Hitler, and the tribe sticks together.
