Incidentally, this was an original motivation for the electoral college:
"Talents for low intrigue, and the little arts of popularity, may alone suffice to elevate a man to the first honors in a single State; but it will require other talents, and a different kind of merit, to establish him in the esteem and confidence of the whole Union, or of so considerable a portion of it as would be necessary to make him a successful candidate for the distinguished office of President of the United States"
It's almost like the very people who came up with the electoral college would be absolutely appalled at the idea that a small handful of states would determine the result of the presidential election...
But why? Besides from actual rallies, appearances, etc, which I doubt have a very significant effect on people's votes (people only go to the rallies of their preferred candidates), there is no reason to target people in big cities. Given that most campaigning happens online or through the media at this point, there is no reason to restrict yourself to geographical areas.
