In 1787 there were no vote-based political parties. So the electoral college being designed specifically designed to destroy third party candidacies is unlikely.

I don't think immigrants, blacks and latinos are segregated to big cities alone. Neither are whites to rural areas. Putting everyone in their own box like you have just done is continuing the divide we all see. Inclusion and diversity is not done by highlighting the differences among race and demanding other races sacrifice for and because of those differences.
