>You should be asking why 70 million people voted the way they did in spite of the events you describe.
Propaganda, 1 in 6 Boomers being exposed to amounts of lead in childhood that lead to measurable cognitive declines, average age of the US population being on the rise with lower birth rates means most eligible votes are in the age groups most likely to suffer low grade dementia, and the weaponization of social media by foreign adversaries and wealthy elites.
There's maybe 4-5M true believers, the rest are gullible lead-addled old fools who got brainwashed by Fox News. That's the unvarnished truth of it.
