As this story shows, the British are finding out how frustrating is the system that chooses a national leader without a democratic process. In the United States only about 20% of the voters effectively matter in the choice of the president because of the electoral college system.
According to Nate Cohn, Donald Trump could lose the national vote by 5 percent and still probably win the electoral college by winning a plurality among that 20% who occupy the swing states.
The British system risks the dissolution of the United Kingdom. The American system threatens the unity of the country and the survival of the republic.
