Your last two paragraphs are so accurate. When people on this site marvel at how anyone can vote for Trump; how Americans can believe the garbage spewed by Maga types; why they’re so beholden to cars, fossil fuels etc, they betray an ignorance about what daily life is like for many millions of Americans (which is fair! I don’t know anything about Hebridean life or Northern Irish life for example!).
That America is rarely seen on TV. The closest glimpse I’ve seen is True Detective, first couple of series. These places are remote; probably had industry and/or agriculture and/or fossil fuel exploitation as their core source of income until some decades ago; probably southern or north western or mid western; probably have churches of whatever denomination to center community. Since those industries died, these places and the people in them have been forgotten in the rush to make $$$$ out of financial services and then tech. Incomes are low, educational aspirations extremely low, employment rates low, quality of life low. These people are exploited by pharmaceutical companies, the military mine them for human fodder, churches bleed them dry. Drug and alcohol addiction are rife. Life’s heyday was back when white people ruled the country, the Cold War was on and communists of whatever colour were the devil, when work was abundant, standards of living could be expected to remain stable or rise. Patriotism was a duty and defined Americanism in such places.
That America has nothing whatsoever in common with the America of Sex and the City, Real Housewives, the America people see on TV.
Now, that America - and there are millions and millions of people like this - vote for Trump because he tells them he hasn’t forgotten them, he wants to make America great again (ie as it was back in that heyday). That he has a proven track record of doing absolutely nothing of the sort, in fact doing the very opposite, means nothing in the face of such a strongly felt hope and recognition he gives them. He makes them feel heard, and he gives them an identity again. The people you saw on Jan 6 descending on D.C. (the “swamp” (recognisable to southerners), full of “elites” (meaning educated coastal Dem voters) etc) in their pick up trucks and Hulk Hogan moustaches and wife beaters etc, those aren’t the Americans you see in Emily Goes to Paris. They’re an entirely different people, with different values and goals.
Like it or not, Trump has changed American politics for an entire generation or more. There’s no going back from what he’s done. Democrats have forgotten those Appalachians, ex miners, ex car factory workers etc, and so did old school Republicans. Both will pay the price for it. There are many many many reasons never to vote for Trump. But nobody else has spoken to that forgotten slice of society (and neither has Trump in reality, he’s just another billionaire telling them he loves them while he plunders them for their last $5, feasting on their desperation and hopelessness and lack of education, bleeding them dry - and when he’s rinsed them of everything they can do for him, he’ll drop them and retreat to his gilded life. But they’ll still believe him, because he made them feel like they matter).
