Trump is a charismatic authoritarian bully, an inveterate lying narcissist, with a man-child mentality. He’s totally unfit to lead, but he will and does appeal to those who like far-right politics, populism, and dislike the social changes posed by feminism, lgbtq rights, multiculturalism, etc.
Trump appeals to those who like strong, right-wing leaders who dislike experts, ignore facts, and who like to work on gut feelings backed up by an ability to work a (dim) crowd into a frenzy with tub-thumping preaching/speeches, populist rhetoric and slogans. He’s a sort of Francisco Franco for the 21st century, and his appeal to JL is guaranteed.
In the 20-teens there was a fashion for this kind of leader (see also Johnson and Farage), largely due to austerity and the ways in which people were persuaded to blame immigration and the EU, rather than the right-wing leaders and their lack of economic control.
Had Trump been a man of the left, he’d (rightly) have been crucified by the right-wing media long ago. It’s only down to press bias that Trump, Farage and Johnson have prospered.
Personally, I see a nightmarish orange person with a rat-clown face whose trousers end up around his ankles every time he speaks.
