Interesting that the more Republican leaning cities seem to be the most integrated. Popular opinion would have said otherwise.

WOW... so it is true that the minorities will soon become the majority in the US? Could someone please give me a roughly % b/c Im partially color blind and I have trouble seeing the whole pictures :|

I mean, NYC is more democratic leaning and it's quite diverse. 

You can tell obvious lines where ethnicities segregate themselves in cities.  Detroit is separated where whites completely surround one completely black area.  In D.C., blacks are on one side and whites on the other, basically.  And NYC is very diverse, with different people living everywhere, for the most part.  California cities are also pretty diverse, unsurprising for both places I think.  Also, I believe Hispanic will be the dominant ethnicity within a few decades, maybe even one or two. 

None of those cities are Republican leaning. Not even Houston or San Antonio. Pretty much all major cities in the U.S. are Democratic leaning.

I actually am off a little.  This CNN article says Hispanics would be the DOMINANT minority ethnicty.  By 2050, about 55% of the popualtion will be minorities.  30% of the population will be Hispanic if rates continue.  They will be the biggest single group, and will be quickly approaching the white total.  So almost 1 out of every 3 people would be Hispanic.  Pretty intersting stuff.

Beat ya to it. Well, at least NYC lol  :p

New York is diverse but doesn't appear to be particularly integrated. From the look of the map it seems like different racial groups are far more segregated than in other areas.

With such a small sample, it is difficult to say whether voting patterns have anything to do with racial integration; but I do wonder if there was a connection would the racial segregation/integration be the cause or result of voting and policy decisions. I would personally suspect that certain "progressive" policies have unintentionally enforced segregation. What I mean by that is fairly simple, initiatives like welfare and public housing (while well intentioned) are known to re-enforce poverty; and those policies (along with other initiatives) may have had the unintended consequence of maintaining racial segregation. On a side note, if this hypothesis was true it would have a potential (awful) side effect of encouraging further intervention in the economy which would (likely) have similarly negative outcomes.

What you said doesn't make sense.  None of those cities are what I'd call Republican leaning cities although maybe one is.

Here is the racial breakdown of all the cities and towns in the US, http://www.city-data.com/

Republican leaning major US cities?  San Diego would be one but there really aren't very many.

Right but the vast majority of hispanics are also white according to the legal terms in the US.  As Spain is part of Europe.
