With the current state-by-state winner-take-all system of awarding electoral votes (not mentioned in the U.S. Constitution, but later enacted by 48 states), it could only take winning a bare plurality of popular votes in only the 11 most populous states, containing 56% of the population of the United States, for a candidate to win the Presidency with a mere 23% of the nation's votes!
But the political reality is that the 11 largest states rarely agree on any political question. In terms of recent presidential elections, the 11 largest states have included five "red states (Texas, Florida, Ohio, North Carolina, and Georgia) and six "blue" states (California, New York, Illinois, Pennsylvania, Michigan, and New Jersey). The fact is that the big states are just about as closely divided as the rest of the country. For example, among the four largest states, the two largest Republican states (Texas and Florida) generated a total margin of 2.1 million votes for Bush, while the two largest Democratic states generated a total margin of 2.1 million votes for Kerry.
In 2004, among the 11 most populous states, in the seven non-battleground states, % of winning party, and margin of “wasted” popular votes, from among the total 122 Million votes cast nationally:
* Texas (62% Republican), 1,691,267
* New York (59% Democratic), 1,192,436
* Georgia (58% Republican), 544,634
* North Carolina (56% Republican), 426,778
* California (55% Democratic), 1,023,560
* Illinois (55% Democratic), 513,342
* New Jersey (53% Democratic), 211,826
To put these numbers in perspective, Oklahoma (7 electoral votes) alone generated a margin of 455,000 "wasted" votes for Bush in 2004 -- larger than the margin generated by the 9th and 10th largest states, namely New Jersey and North Carolina (each with 15 electoral votes). Utah (5 electoral votes) alone generated a margin of 385,000 "wasted" votes for Bush in 2004. 8 small western states, with less than a third of California’s population, provided Bush with a bigger margin (1,283,076) than California provided Kerry (1,235,659).
