Yes both UK & US electoral systems are dreadful and rarely fully representative of peoples views. But. Its all very well commentators constantly bemoaning useless or misguided politicians who entrench inequality and trash the planet.
But 77.3 million people left their homes and voted for this man, knowing very well from 2016-20 what he was. Margaret Thatcher sold off public housing, generating the housing crisis, was belligerent and xenophobic, trashed the old industrial cities. Millions in Britain worshipped her and voted for her and her spiritual successors including Blair, Cameron etc time and again. 52% of EU Referendum voters in 2016 went out and voted to leave the world's most successful free trade block. Nigel Farage says the most appalling things about other humans and is set to become Prime Minister. Millions and millions of voters are responsible for what has been done to both countries.
