This is funny, If I put 100% Citizenship/100% Voting and give Obama 100% for all the nonwhite vote, Dems only need 13% of the white vote to win the election by 2048. 
You don't like that do you?
No, I'm fine with it. Whoever wins the most votes should win, IMO. It's just interesting how sliding the scales different ways can give very, very different results.
The glaring thing that playing with this map has brought home to me is how very important it is to keep at least in the high 30s of whites voting Democratic. As Skill-and-Chance points out, a deterioration in the white vote percentage can create a huge electoral vote deficit even while the Democrats win narrowly in popular vote. Terrifying.
What's more terrifying is that more and more whites are less than 3 months(or however long they can "couch surf" when they lose their employment) away from homelessness/death and yet they vote more and more Republican. The precariously positioned white working class seems be hungry for the "iron fist".
