This would think out the representation significantly, and applied to presidential voting would be rather dificult. The highest share of eligible voters in US history to support a US President is 42.6% for Ulysees S. Grant (Harrison and McKinley both close behind with +40%). Not one President has ever broken the 50% of eligble voters mark, and even those presidents that won in relative landslides in the EC (Washington, Monroe, Roosevelt, Reagan, Nixon) all had shares of the eligible votes that were in the 30%’s.
