#8. Boris Johnson
For Americans, the shorthand on Boris Johnson is that he’s something like the British Donald Trump, right down to the confounding hairstyle. The U.K.’s Secretary of State for Foreign and Commonwealth Affairs’ endorsement of the Brexit campaign is at least partially responsible for its passing, which sent international markets into a steep decline. The move caused what some called “the greatest constitutional crisis of modern times.” Then, after President Obama urged U.K. voters to stay in the EU, Johnson accused him of harboring “an ancestral dislike of the British empire” due to his Kenyan heritage.
