If you add up all the runner-up votes and all the surplus votes cast for president, then the total is about 60%. Let's repeat that: about 60% of all votes cast for president under the current system do not matter at all. They are "systematically discarded," in the good phrase of lawsuits catalyzed by the brilliant Larry Lessig of Harvard Law School. It's a wonder as many people vote as do vote given how many votes the system ignores.
