America is a white Protestant country majority of whom live in poor rural areas.
They are conservative and racist to the hilt though they try to hide it.
Trump knew this was the electorate to win with his rhetoric and knew most were not enlightened and ignorant of the world outside their own small neighbourhoods.
He would undoubtedly have won if the Democrats and Republican liberals had allowed it.
so how do you get to his electorate.
Their hypocritical puritanical Elizabethan Christianity. The supposedly chastity, virginity,monogamy, celibacy religious/moral view that haunts both the Americans and the United kingdom politicians.
They have used this with devastating effect and organized a concerted effort by both the political establishment across the divide Government operatives and the media to thwart and destroy Trumps candidature, after a realization that a Trump's win would be a catastrophically embarrassing affair, that would never allow America again to hold its head up high and moralize on the rest of the world.
