Wow!!! Fantastic job reagente!! Congrats! 
The map is amazing. The white electorate in Detroit, Indianapolis and Atlanta voted for Trump. That result surprised me because i believed that the white vote in these areas was extremally liberal. Is there any reason for this? Is the AA vote so high in these counties that overshades the white vote?
PS: Just off topic, reagente are you portuguese?
The margins were pretty close in all of these, and I suspect that Clinton won the White vote in the city proper for all of these cases, but the other suburbs in the county put Trump over the edge.
Per this model, Trump won the White Vote in Marion County, IN by 3.2%, Wayne County, MI by 0.4%, and Fulton County, GA by 2.5%.
Very few whites live in Detroit proper and putting minority turnout at the same as whites and as 100% for Clinton still leaves Detroit whites as solidly Democratic. Indianapolis incorporates almost all of Marion County, so Trump likely carried Indianapolis whites. Not quite sure about Atlanta, especially because it continues into DeKalb county, but it's probably close either way.
Other major central cities in counties that Trump appeared to carry whites are Phoenix, Jacksonville, OKC, where Trump won outright, and Dallas, Houston, San Antonio, Tampa, Orlando, Charlotte, Memphis, Kansas City, Cincinnati, and Buffalo.
