It would be totally unfaor to rural areas and small cities. Candidates will not waste their time going to Podunk, New Jersey when there are 20 times the voters in Atlantic City.
The people are different in smaller towns with smaller needs but must be heard just as the voters in the big cities. That could only happen with the electoral college.
Actually the candies wouldn't go to anywhere in New Jersey because the red candidate knows he can't win and the blue one knows he's got it in the bag, so what's the point?
Thank the WTA/EC for that gem.
Now if it were counted proportionally there would actually be reason to go to New Jersey, incluidng Podunk, you'd draw a crowd bigger than Podunk's own population, and all the other Podunks would relate - "look, a small town just like us" --- because the population of Podunk or AC in no way determines how many people are gonna show up.
PLUS the fact that the more warm bodies that DO show up, the less intimate and connected the setting is, so what have you really accomplished other than a photo op.
