why go for:
Delaware = 925,749
South Dakota= 844,877
Alaska = 735,132
North Dakota= 723,393
Vermont = 626,630
Wyoming = 582,658
Total = 4,43,8435
When you can focus all of your attention on New York City alone (not even the whole state) and get over 8 million. Far cheaper and yields greater returns. Electoral college might not work but a populus vote craps on states like the ones mentioned.
EDIT: apparently what I'm trying to say isn't clear enough for some people.
Even convincing half of new york city (not state just city) to vote for you yields roughly the same amount of vote as convincing all of Rhode island, Delaware, South Dakota,Alaska,North Dakota, Wyoming, and Vermont to vote for you. And that's just half of the city.
