Yeah, I know cities tend to vote liberal, but DC has always seemed extreme to me, even accounting for that. I mean, I don't have data for how big cities vote in general, but I thought it was something like 70% liberal. A solid majority and dissenters.

But DC voted 93% Democrat in 2008. 93! That's not a majority. That's a consensus.

It's on the high end, but I think around 80-90% Democratic for an urban core is fairly common. It's hard to get exact numbers because it depends on where lines are drawn. For example, Cook County (where Chicago is located) "only" voted 76% Obama, but it includes a number of suburban areas, and would be >80% if you pruned them.

Here are the next-most-Democratic cities I came across in some spot-checking, with NYC boroughs broken out b/c they're separate counties: 89% Bronx (NYC), 86% Manhattan (NYC), 84% San Francisco, 80% Brooklyn (NYC), 79% Boston, 79% Alameda County (East Bay), 77% Portland.

Silicon Valley is closer to the 70-ish you're thinking of, but it includes a number of quite suburban areas. Obama won 74% in San Mateo County, and 70% in San Jose County. LA County is about the same (70%), as is Fulton County (Atlanta).

> 70% in San Jose County

Santa Clara County? :-)

> LA County

Sorry, I guess we're a bit overly fussy out here. That one would be Los Angeles County. (Not that you couldn't call it LA County, just doesn't sound quite right. It's not uncommon to abbreviate the city to LA, but not so much the county.)

[javajosh]

Not only irrelevant, but also wrong. We say "LA County" all the time.

[Stratoscope]

Ah, you and _delirium are right, sorry. That's what I get for posting late at night.

[_delirium]

Oops, you're right on Santa Clara County. LA County is fairly common though I think.

DC is fed by US government.

Democrats are pro-government, so DC votes for Democrats.

More info:

- Many in the DC metro area are also employed by the military or employed by proxy (i.e. working for a contractor like Boing/Lockheed/Caci/etc.).

- The military is a part of the government.

- The republican party is firmly behind the military.

Unsurprisingly the outlying suburbs of the DC metro area are lean republican[1].

Looks like everyone is voting for their own interests here.

I don't think that's true of the past decade or so. While DC's outlying suburbs in Virginia and Maryland are more Republican than the urban core, they most certainly vote more Democratic than the average suburban county elsewhere in the U.S.

It's possible that is a factor, but DC is >50% black, so it wouldn't be surprising to see a huge majority for Obama in 2008.

[ohashi]

It's about 50% (50.7) http://quickfacts.census.gov/qfd/states/11000.html

[waterlesscloud]

It's been as high as 71.1% Black (in 1970). The percentage has been decreasing as Blacks have moved to the suburbs and Hispanics have moved into the city.

[pilom]

Well, I would argue a large number of young white professionals have moved in to and are gentrifying many parts of DC.

[ohashi]

I agree that this is the bigger trend changing the demography of DC. Neighborhoods like Columbia Heights, Petworth, etc.

The metro DC region is one of the most educated areas of the country. This is the reason why the area leans more blue than red.

Cities are necessarily liberal entities, and people who live in cities tend to vote for more liberal parties.
