LOL.
Obama won election with the fewest recorded number of American counties, just 24. NPV would reduce that to just two - Cook County and LA county.
You could run an entire election out of just those two.
Ben Kenobi maths:
Population of Cook County - 5.24 million
Population of LA County. - + 10.02 million
____________
15. 26 million
Population of United States - 318.9 million
15.26 million / 318.9 million = 0.0479
Therefore, we can test B. kenobi's hypothesis:
0.0479 > 0.5
By Jove! You're right! Focusing on only 4% of the American population, in a densely packed, expensive media market would easily win an election! What a genius you are!
