Crazier electorate, that's how (you have the understand the population first to understand why a Trump could thrive).
One where over 40% of the population are young Earth creationists who believe the planet is 6000 years old and that man walked with dinosaurs. The place is a haven for cults (Mormons, Jehovah witnesses, Seventh-day Adventists etc. etc. among the bigoted sects developed there...every November with "thanksgiving" they commemorate another persecuting cult (Puritans) getting fed by the Natives (a people they dehumanized as "savages" in the white settler colonial document the 'declaration of independence', then ethnically cleansed, massacred, and, to quote Hitler in 1929, "put the modest remnant under observation in a cage"). The country itself is a cult..televangists, megachurches, children having to pledge allegiance (and they still sing that slave song (with words by the slave owning tyrant Francis Scott Key) as the national anthem, omitting the third verse which condemned the slaves for having the audacity to defect to the British who gave them freedom). Another religious/white supremacist group, Ku Klux Klan, had four million members there, terrorising non white people (their favourite pastime). Race mixing (interracial marraige) was "unbiblical", with Harry Truman in 1963 saying.."I don’t believe in it. Would you want your daughter to marry a Negro? She won't love someone who isn't her color." It's also the home of UFO sightings. Trump wouldn't get a sniff of being elected in any other "civilised" nation.
There religion is everybody's business, you have zero chance of being elected otherwise. Trump being an atheist, seeing him 'profess his faith' is something only a swathe of gullible people could buy what with him not being able to name a single Bible verse, and when asked whether he enjoys the Old Testament or the New Testament, said: "Probably equal. I think it's just an incredible... the whole Bible. I think it's just incredible. The whole Bible is incredible."
In relation to the america backed massacre now going on in Gaza (24000 killed), this backing is also cult based.... "Trump is a fan of Evangelical pastor and Fox contributor Robert Jeffress who previously called Trump a "Christian warrior" and said that removing him from office would create a "Civil War-like fracture" in the US, and also once said Jews were going to hell but also prayed to "bless those who bless Israel and curse those who curse Israel".
