The Electoral College is very difficult, almost impossible to change. So we have a Future America with more colors of Black, Brown, Yellow or Red.
By a Great Irony of Destiny and Fate, the Electoral System was always supported by the most Conservative, "Constitutionalist", "Pro American" or "Patriotic" Americans. But the Sarcasm of Fate is that the Electoral System now favors the Liberals and Democrats, who happen to be the most friendly people to the "New Americans" and the most "compassionate" or progressive towards a New America.
The Swing States are more Tropical ( or Subtropical ), they have more non-White People for Historical Reasons, but also because the Minorities originally came from warm lands.
These Minorities are very young, a low proportion of them are new immigrants of the last 20 years. To me they appear very energetic and thrown to the future.
It is very ugly to think of Human Beings as dogs, horses or flowers in biological terms. But many millions think like that. I give you an example : Racists like Rush Limbaugh, Glenn Beck, Jan Brewer, Kris Kobach, Russell Pearce, Pete Wilson and Mitt Romney that is in bed with them.
There is another current of Biology, Zoology or Anthropology that thinks that Hybridization is not so bad and that Human Beings are the product of many miscegenations and Hybridizations. Like the Maize of Prosperous Productive Fields.
A country does not progress because there are angry people in Temper Tantrums like Rush Limbaugh, what a country needs is new blood.
That the New Americans are darker ( less White ) or "uglier" in Hollywoodesque stereotyping is an accident of Fate or Destiny.
My bet is that the New Americans will take the Greatest Nation in History, the most inventive country to new heights, even if they are perceived with fear and many people are scared of them.
And so the Electoral College won't be significantly modified or only to accommodate more subtropical Electoral Votes of Swing States with more Black, Brown, Yellow or Red people.
