Look at the 2004 county-by-county map.
Kerry had only, what, 2-3 million less votes than Bush. All his votes were in New York, LA, Chicago, San Fran, and other large population centers. Without an electoral system, he could have focused almost exclusively on these cities, not giving a flying fig about anyone in Nebraska, Iowa, the Dakotas, etc.
Perfect example, Ohio.
Kerry could have made promise after promise to Cleveland, Cincinnati and Columbus. That is really all he'd need (ok, maybe Toledo as well). He could completely ignore the rest of the state.
The electoral college works to balance this out.
If I was a suspicious type, I'd say that you're only angry about the system because Kerry lost. Its the same thing the democrats did in 2000.
